Synergistic Effect of Oxygen and Water on the Environmental Reactivity of 2D Layered GeAs

The Journal of Physical Chemistry C, Journal Year: 2025, Volume and Issue: 129(2), P. 1173 - 1182

Published: Jan. 6, 2025

We investigated the reactivity of layered GeAs in presence oxygen or water using synchrotron-based X-ray photoelectron spectroscopy and ab initio calculations. By performing experiments at near-ambient pressure (up to 20 mbar), we gained detailed insights into material's stability under realistic conditions. showed limited with dry O2 deaerated H2O. However, a small amount humidity (Rw = 0.5% T °C) an atmosphere significantly enhanced reactivity. This synergistic effect was well captured by density functional theory calculations, which revealed strongly exothermic formation energy for simultaneous chemisorption H2O, compared adsorption each molecule individually.
