Generalized Einstein relation for nonparabolic multiple energy-band degenerate semiconductors

open access: yesAIP Advances, 2019
A generalized Einstein relation for electron gases of degenerate semiconductors with a system of typically two nonparabolic conduction band structures is derived and formulated in near-equilibrium condition based on using the semiclassical drift ...

The band energy structure of RbKSO4 crystals

open access: yesCondensed Matter Physics, 2007
The energy band structure of mechanically free and compressed RbKSO4 single crystals is investigated. It is established that the top of the valence band is located at the D point of the Brillouin zone [k = (0.5, 0.5, 0)], the bottom of the conduction ...

Investigation of energy band at atomic layer deposited AZO/β-Ga2O3 ( 2¯01 $$ \overline{2}01 $$) heterojunctions

open access: yesNanoscale Research Letters, 2019
The Al-doped effects on the band offsets of ZnO/β-Ga2O3 interfaces are characterized by X-ray photoelectron spectroscopy and calculated by first-principle simulations. The conduction band offsets vary from 1.39 to 1.67 eV, the valence band offsets reduce

Nanoscale active tuning of the second harmonic generation efficiency in semiconductors from super-low to gigantic values

open access: yesNew Journal of Physics, 2022
Second harmonic generation efficiency (SHGE) strongly depends on the length of the interaction material along the beam propagation axis. Since a nanoscale interaction length is considered too short even in the optical wavelength scale, the attained SHGE ...

Determination of the surface band bending in InxGa1−xN films by hard x-ray photoemission spectroscopy

open access: yesScience and Technology of Advanced Materials, 2013
Core-level and valence band spectra of InxGa1−xN films were measured using hard x-ray photoemission spectroscopy (HX-PES). Fine structure, caused by the coupling of the localized Ga 3d and In 4d with N 2s states, was experimentally observed in the films.
