Luminescence of crystals ZnSe <Al>:Gd
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2018, Vol 21, Issue 1
Abstract
It has been experimentally shown that the luminescence spectra of ZnSe <Al> crystals doped with Gd from the vapor phase contain two mutually compatible luminescence bands. It is established that the low-energy G-band is due to recombination with association of complexes and , and the boundary B-band is the result of annihilation of excitons and interband transitions.

Semiconductor surface spectroscopy using transverse acousto-electric effect: Role of surface charge in photo-processes at the ZnS/Si interface
The effect of illumination in the visible spectral range on the magnitude of transverse acoustoelectric effect (TAE) in ZnS/Si structures was studied using a noncontact surface acoustic wave device based on the acoustoel...

The influence of the exciton non-radiative recombination in silicon on the photoconversion efficiency. 1. The case of a long Shockley–Read–Hall lifetime
By comparison of the experimental dependence of bulk lifetime in silicon on the doping and excitation levels with theoretical calculations, it has been shown that a new recombination channel becomes operative when Shockl...
