HIGHLIGHTED ARTICLES Editors' Suggestion Monitoring the Charge-Carrier-Occupied Density of States in Disordered Organic Semiconductors under Nonequilibrium Conditions Using Thermally Stimulated Luminescence Spectroscopy Andrei Stankevych, Rishabh Saxena, Alexander Vakhnin, Falk May, Naomi Kinaret, Denis Andrienko, Jan Genoe, Heinz Bässler, Anna Köhler, and Andrey Kadashchuk Phys. Rev. Applied 19, 054007 (2023) – Published 2 May 2023 Injected or photogenerated charge carriers in disordered organic semiconductors relax in energy to form an occupied density of states (ODOS) that is inherently difficult to probe. Thus little is known about nonequilibrium ODOS properties, although they are important in e.g. solar cells and LEDs. This work presents an optical technique for monitoring the ODOS distribution of relaxed charge carriers at low temperatures. The distribution that forms under nonequilibrium conditions is always narrower than that of the full DOS, in a universal ratio of about 2/3 that is reproduced by kinetic Monte Carlo simulations assuming spatially correlated disorder.

Gemmell, Jefferson Flórez, Emma Pearce, Olaf Czerwinski, Chris C. Phillips, Rupert F. Oulton, and Alex S. Clark Phys. Rev. Applied 19, 054019 (2023) – Published 5 May 2023 Sensing with undetected photons is a fascinating technique that allows imaging at wavelengths outside a particular detector’s range—enabling, for example, biological imaging without perturbing live cells. In this interference technique, performance can be very sensitive to both sample transmission and losses. This study shows that by balancing the nonlinear interferometer’s arms, one can completely recover fringe visibility caused by signal loss. Moreover, intentional unbalancing offers a reduced-interaction regime where the detected power can be 200 times higher than the power reaching the sample, for ultrasensitive midinfrared sensing well below the conventional noise floor.

So far, readout capabilities and device coherence have been limited by lossy I I I − V substrates, but here researchers overcome this limitation with a flip-chip approach to microwave experiments on ABSs. Superconductor-semiconductor devices and microwave resonators are placed on different chips and inductively coupled via a vacuum gap, enabling high-quality readout without sacrificing device properties.

Rev. Applied 19, 054028 (2023) – Published 9 May 2023 Long-range couplings beyond the nearest neighbors can trigger exotic topological phases in metamaterials but have been overlooked in many topological models. The authors study the effect of the long-range couplings on the topological properties, and demonstrate that a Su-Schrieffer-Heeger model including the third nearest coupling, implemented by acoustic metamaterials, can lead to topological phases of large winding numbers. The experimental results show additional topological end states and rotonlike dispersions for sound waves, highlighting the potential of these long-range metamaterials in creating rich topological features.

Rev. Applied 19, 054052 (2023) – Published 16 May 2023 Lithium niobate (LN) devices have been widely adopted in systems for quantum key distribution (QKD), but the photorefractive effect in LN devices can be exploited as a potential loophole for malicious attacks by eavesdroppers. This work points out a vulnerability of LN devices of which manufacturers and users must become aware, so that appropriate countermeasures may be implemented.

Rev. Applied 19, 054054 (2023) – Published 16 May 2023 Understanding nonradiative recombination is important for improving semiconductor devices. For Cu(In,Ga)Se 2 (CIGS) solar cells, antisite defects have long been considered the main recombination centers, yet the underlying mechanism has remained elusive. Here first-principles calculations show that these “killer centers” themselves cannot capture holes efficiently for effective recombination. However, internal conversion to the distorted neutral DX center does open an efficient hole-capture pathway, and DX’s stability in CIGS increases with Ga concentration, which resolves the longstanding issue of why the efficiency of CIGS solar cells decreases at high Ga concentration.

Through multiple state-of-the-art microscopy techniques the authors visualize Ag + migration in AgBiP 2 Se 6 , and how it modulates the interfacial barrier to induce switchable diodelike transport in a device.

Rev. Applied 19, 054056 (2023) – Published 17 May 2023 “Ugh, not again! Something’s wrong with this printer…” In inkjet printing the nozzles in the printhead have intermittent idle periods, during which the ink can evaporate from the nozzle exit. Inks are usually multicomponent, and each component has its own characteristic evaporation rate, resulting in concentration gradients within the ink that can alter the jetting process.

The authors demonstrate a reliable, automated method to identify the capacitive coupling between QDs. The approach combines machine learning with traditional fitting, to take advantage of the desirable properties of each. Also, analysis of cross capacitance may be used for automatic identification of the spurious QDs that occasionally form during device tuning. These techniques can autonomously flag devices with spurious dots near the operating regime, which is crucial information for reliable tuning for qubit operations.

The authors solve the technical challenges and demonstrate a microwave-frequency NV magnetometer with picotesla sensitivity, by implementing a pulse scheme for noise cancellation and employing a custom-grown diamond. This sensitivity enhancement could be extended into a far broader range of frequencies using spin-locking and quantum frequency mixing.

Rev. Applied 19, 054052 (2023) – Published 16 May 2023 Lithium niobate (LN) devices have been widely adopted in systems for quantum key distribution (QKD), but the photorefractive effect in LN devices can be exploited as a potential loophole for malicious attacks by eavesdroppers. This work points out a vulnerability of LN devices of which manufacturers and users must become aware, so that appropriate countermeasures may be implemented. Moreover, the physical mechanism and techniques introduced in this work open an important avenue to the security analysis of QKD systems.

Rev. Applied 19, 054054 (2023) – Published 16 May 2023 Understanding nonradiative recombination is important for improving semiconductor devices. For Cu(In,Ga)Se 2 (CIGS) solar cells, antisite defects have long been considered the main recombination centers, yet the underlying mechanism has remained elusive. Here first-principles calculations show that these “killer centers” themselves cannot capture holes efficiently for effective recombination. However, internal conversion to the distorted neutral DX center does open an efficient hole-capture pathway, and DX’s stability in CIGS increases with Ga concentration, which resolves the longstanding issue of why the efficiency of CIGS solar cells decreases at high Ga concentration.

Rev. Applied 19, 054055 (2023) – Published 16 May 2023 Ionic migration in solid phases is actively explored as a mechanism for neuromorphic computing elements, for example, but direct imaging of the ionic migration and its correlation with macroscopic electronic transport are tricky. Through multiple state-of-the-art microscopy techniques the authors visualize Ag + migration in AgBiP 2 Se 6 , and how it modulates the interfacial barrier to induce switchable diodelike transport in a device. Illuminating the device can be used to switch off its ionic tunability, expanding its functionality. These results provide direct insight into the mechanism of ion-mediated transport in ionically active semiconductors.

Something’s wrong with this printer…” In inkjet printing the nozzles in the printhead have intermittent idle periods, during which the ink can evaporate from the nozzle exit. Inks are usually multicomponent, and each component has its own characteristic evaporation rate, resulting in concentration gradients within the ink that can alter the jetting process. Through experiments, analytical modeling, and numerical simulations, the authors unravel the complex physicochemical hydrodynamics associated with the drying of ink at a printhead nozzle.

The authors demonstrate a reliable, automated method to identify the capacitive coupling between QDs. The approach combines machine learning with traditional fitting, to take advantage of the desirable properties of each. Also, analysis of cross capacitance may be used for automatic identification of the spurious QDs that occasionally form during device tuning. These techniques can autonomously flag devices with spurious dots near the operating regime, which is crucial information for reliable tuning for qubit operations.
