Gate‐Tunable Polarity‐Reconfigurable Photovoltaic Response With Dual Linearity in NbS3/WSe2 Heterostructures for In‐Sensor Image Processing

open access: yesAdvanced Science, EarlyView.
An NbS3/WSe2 van der Waals heterostructure realizes a continuously gate‐tunable self‐powered photovoltaic response through interfacial band‐alignment modulation and reversible built‐in electric‐field switching. The short‐circuit photocurrent scales linearly with incident power density, while short‐circuit photoresponsivity varies linearly with gate ...

Ultrathin 2D In2O3 Nanosheets Confining Cu Single Atoms Synergized With Oxygen Vacancies for High Selectivity of Photocatalytic Reduction of CO2 to CO

open access: yesAdvanced Science, EarlyView.
In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure based on oxygen vacancies (OV)‐rich defects and low crystallinity to anchor Cu single atoms (Cu SAs) and synthesized Cu/In2O3‐Ns photocatalysts. ABSTRACT In this work, we constructed an ultrathin two‐dimensional (2D) In2O3 nanosheet (In2O3‐Ns) structure ...
