Temperature, Absorption and Excitation Study of the A(1-x)B(x)C Crystals by Raman Scattering Methods
Abstract
Recently, wide gap II-VI mixed crystals are studied for their application in technology of blue-green laser diodes. The mixed crystals were grown using the modified pressure Bridgman method. The temperature, absorption and excitation study of Zn(1-x)A(x)Se mixed crystals using Raman scattering method is reported. Measurements have been performed for crystals with x = 0.07 for A = Mg content and x = 0.09 for A = Be content. The Raman scattering spectra were obtained for different temperatures and different excitation wavelengths. From the Raman spectra the longitudinal optical (LO) and transverse optical (TO) modes which correspond to ZnSe-, MgSe- and BeSe-like single crystals were distinguished. For all used excitation wavelengths and different temperatures the integrated intensities of LO and TO modes using a curve-fitting method have been calculated.
