Scanning photocurrent microscopy reveals electron-hole asymmetry in ionic liquid-gated WS2 transistors

, 2014
We perform scanning photocurrent microscopy on WS2 ionic liquid-gated field effect transistors exhibiting high-quality ambipolar transport. By properly biasing the gate electrode we can invert the sign of the photocurrent showing that the minority ...

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

Engineering Bilayer Tandem Catalysts on Si‐Based Photocathodes for High‐performance CO2 Reduction to Produce Methane

Advanced Materials, Volume 38, Issue 15, 12 March 2026.
A Cu/Ag‐Cu bilayer tandem catalyst is designed for a pyramid‐structured p‐Si photocathode, creating multiple and functionally distinct interfaces tailored to specific reaction steps and intermediate stabilization. This Cu/Ag‐Cu‐decorated p‐Si photocathode exhibits both high photocurrent and good selectivity for photoelectrochemical CO2 reduction to CH4.
