Juntong LiYanping NiYichun Liu ArticleOpen Access26 Jul 2024 Broadband nonreciprocal thermal emissivity and absorptivity Nonreciprocal thermal absorptivity and emissivity is shown over a broadband spectrum and specified angular range for a gradient epsilon-near-zero photonic structure. Komron J. ShayeganJae S. HwangHarry A. Atwater ArticleOpen Access24 Jul 2024 A memristive-photoconductive transduction methodology for accurately nondestructive memory readout A memristive-photoconductive transduction (MPT) behavior was firstly observed in a memristor based on porous P3HT, which is the direct signal for cell resistance states detection, enabling accurate and nondestructive readout. Zhe ZhouYueyue WuJuqing Liu ArticleOpen Access23 Jul 2024 Bottom-up construction of low-dimensional perovskite thick films for high-performance X-ray detection and imaging The quasi-two-dimensional perovskite films were successfully fabricated through a precisely controlled crystallization process by utilizing a mixed atmosphere of CH3NH2 and NH3, resulting in the development of an ultra-sensitive perovskite/TiO2 heterojunction X-ray detector.
