LOW-TEMPERATURE RAMAN SCATTERING SPECTRA AND ELECTRICAL PROPERTIES OF Cd_(1-x) Zn_xTe(x=0.04) OF DIFFERENT SURFACE TREATMENTS
Cd_(1-x)Zn_xTe(x=0.04)表面处理的低温拉曼散射和电学特性研究

Fourier transform Raman scattering spectra and current voltage ( I V ) features were measured for Cd 1 x Zn x Te( x =0.04) surfaces of different treatments. By analyzing the anti stokes Raman spectra and comparing with surface current voltage ( I V ) curves, it was concluded that the behavior of the lattice phonons which are associated with surface treatments reflects the perfection variation of Cd 1-x Zn x Te( x =0.04) surface. It was also found that Te precipitates on Cd 1-x Zn x Te( x =0.04) surface are crucial to surface quality. In addition, potential application of the different surface treatments was discussed.
