Identifying chemical and physical changes in wide-gap semiconductors using real-time and near ambient-pressure XPS

“…[16][17][18] However, additional measurements are required to identify the inuence of sample inhomogeneity and the inuence of the measurement method such as nal state effects, radiation damage and surface charging. 19,20 Here we show how different mechanisms are responsible for the observed core level binding energy changes for a metal alloy and two wide-gap semiconductors when the temperature is cycled between room temperature and 600 C. Using real-time and near-ambient pressure XPS, where temperature and pressure are the only variables, the dominant physical and chemical effects are identied and corrected.…”

Influence of Codoping on the Optical Properties of ZnO Thin Films Synthesized on Glass Substrate by Chemical Bath Deposition Method

“…Zinc oxide is an amazing material for numerous applications such as photodetectors, antireflecting coating, thin film solar cell, LEDs, and lithium-ion batteries [1][2][3][4][5] due to its wide band gap (3.445 eV) and high binding energy (60 eV) [1,6]. Due to its unique optical, semiconductor, and optical properties, ZnO thin films have been extensively studied for various applications.…”
