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 ...

Record Negative Photoconductivity in N‐Polar AlGaN/GaN Quantum‐Well Heterostructures

open access: yesAdvanced Photonics Research, EarlyView.
The negative photoconductivity (NPC) effect is experimentally observed in the N‐polar AlGaN/GaN quantum‐well heterostructures after introduction of a GaN/AlN superlattice back barrier. The NPC phenomenon appears in the N‐polar AlGaN/GaN quantum‐well heterostructures under infrared light illumination at room temperature.

Dynamically Tunable Coherent Perfect Absorption Based on Bound States in the Continuum in Borophene Metamaterials

open access: yesAdvanced Photonics Research, EarlyView.
This article proposes a symmetry‐protected bound states in the continuum mechanism based on borophene metamaterials, achieving dual‐band broadband coherent perfect absorption (CPA) in the near‐infrared spectrum. By dynamically modulating carrier concentration, the operational bandwidth of CPA can be significantly expanded, effectively overcoming the ...
