| Abstract: | 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. |
