The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

Advanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

XPS AND AES STUDY OF AlxGa1-xP SOLID SOLUTIONS

Acta Physica Sinica, 1985
The solid solution AlxGa1-xP(0≤x≤0.64) has been investigated by XPS and ABS.The experimental results show that the binding energy of P21, core level decreases and the top of the valence band recedes with increasing Al-content. Moreover the weak Auger peaks of GaP have been identified and clarified.
