Elemental Core Level Shift in High Entropy Alloy NanoparticlesviaX-ray Photoelectron Spectroscopy Analysis and First-Principles Calculation

“…The work function of each sample was calculated according to Equation , and found to be 4.50 eV, 4.45 eV, and 4.50 eV for Mg@CNF, Cr@CNF, and Mn@CNF where hν is the excitation energy of He­(I), 21.2 eV.…”

Approaching Theoretical Band Gap of ZnSnN2 Films via Bias Magnetron Cosputtering at Room Temperature

“…45 Figure 1. Comparison of experimental band gap energy obtained in the literature (colors) for ZnSnN 2 , using different methods of synthesis at different deposition temperatures (symbols), with the calculated band gap energy and the experimental optical band gap energy of this work 2,4,5,7,9,11,[18][19][20][21][22][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] So far, few works have investigated oxygen contamination in ZnSnN 2 thin films. A previous experimental work, accomplished in our group, highlighted the content of oxygen at the column boundaries, by EDS measurements in STEM mode and Mössbauer experiments.…”

Evaluation of Band Alignment of SrNbO2N Using Hard X-ray Photoelectron Spectroscopy

“…Ultraviolet photoelectron spectroscopy is commonly used to evaluate the valence band position. However, the spectrum is sensitive to the surface condition . Oxynitrides have a higher degree of freedom in atomic coordination compared with oxides, and the coordination state of the atom affects its electronic structure, such as valence band positions; therefore, examining the atomic coordination is indispensable for an accurate evaluation of its electronic structure.…”
