Published in 2017 at "Journal of Materials Science"

DOI: 10.1007/s10853-017-1394-x

Abstract: Aimed at improving the actual photoemission performance of nanowire photocathode, an axial exponential-doping GaN nanowire photocathode is proposed. Based on two-dimensional continuity equation and finite difference method, the quantum efficiency of this exponential-doping GaN nanowire… read more here.

Published in 2023 at "Materials"

DOI: 10.3390/ma16031227

Abstract: Polarization doping in a GaN-InN system with a graded composition layer was studied using ab initio simulations. The electric charge volume density in the graded concentration part was determined by spatial potential dependence. The emerging… read more here.
