The fabrication cost of the semiconductor device is increasing because the fabrication cost per wafer unit area and the mask cost are increasing rapidly with the design rule decreased. The rapid increase in the mask cost will influence the semiconduc

The absorption and luminescence spectra were observed below 77°K by using a high resolution spectrograph. The crystal field spectra show that the structures of some Tm 3+ centers are common to both of ZnSe:Tm, Cu and ZnSe:Tm, Li crystals. One of the

The polarized infrared absorption due to the fundamental and 2nd-harmonic excitation of the localized vibration of Be in CdS and CdSe is observed. The splitting and the polarization property are in accord with C 3 ν point symmetry of Be impurity. Th

The localized vibrational modes of Be in ZnS and ZnSe are observed by using the infrared absorption and Raman scattering. The concentration dependent shift of local mode line is found in ZnS: Be. For these systems, anharmonic potential constants are
