Band Alignment and Composition of the Buried TiO2/GaInP Interface

Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
Buried TiO2$\text{TiO}_2$/GaInP interfaces formed by mild plasma‐enhanced ALD are shown to be largely insensitive to the initial GaInP surface condition. Angle‐dependent photoelectron spectroscopy reveals similar interfacial chemistry and band alignment for phosphorus‐rich and naturally oxidized surfaces, demonstrating a robust pathway for reproducible
