Synergistic Effect of Compositional Engineering and Graded Heterojunction Formation in Tin‐Halide Perovskites for Near‐Infrared Photodetectors

open access: yesAdvanced Optical Materials, EarlyView.
The compositional engineering of Sn‐halide perovskite with alkylammonium chloride, combined with graded heterojunction formation using fullerene, is shown to significantly enhance crystallinity and reduce trap densities. Consequently, the resulting photodetectors achieve a 63.4% external quantum efficiency and a specific detectivity of 1.38 × 1011 ...

Origin of Ultraviolet‐Induced High‐Temperature Photovoltaic Response at Pt/Gd‐Doped CeO2 Interface

open access: yesAdvanced Optical Materials, EarlyView.
Oxygen uptake induced by UV irradiation generates an oxygen chemical potential gradient across acceptor‐doped ceria at high temperatures. Besides the photovoltage caused by band bending at the heterojunction interface, the observed voltage can also be attributed to the Nernst voltage arising from the oxygen potential gradient.

Light Intensity‐Controlled Photoconductance Polarity Switching for Neuromorphic and Logic Applications

open access: yesAdvanced Optical Materials, EarlyView.
Light intensity‐induced photoconductance polarity switching is demonstrated in geometrically asymmetric Schottky MoSe2 devices. The devices exhibit bidirectional reconfigurable optoelectronic logic gates and synaptic applications using a single light source, opening new avenues for multifunctional optoelectronic and neuromorphic computing systems ...
