Abstract Providing sufficient driving force for charge separation and transfer (CST) is a critical issue in photoelectrochemical (PEC) energy conversion. Normally, the derived mainly from band bending at photoelectrode/electrolyte interface but negligible bulk. To boost bulky force, we report rational strategy to create effective electric field via controllable lattice distortion bulk of semiconductor film. This concept verified by lithiation classic TiO 2 (Li-TiO ) photoelectrode, which...

Monolayer (ML) transition-metal dichalcogenides are considered as promising channel materials in next-generation transistors. Using ab initio energy band calculations and more reliable quantum transport simulations, we study the interfacial properties of ML MoSe2–metal interfaces (metals = Al, Ag, Pt, Cr, Ni, Ti). Weak or medium adsorption is found between MoSe2 Pt surfaces with structure preserved, while strong Ti, Cr destroyed. The two methods give similar polarity height Schottky barriers...
