Description

Cd2GeSe4 films were grown by using conventional thermal vacuum evaporation. X-ray diffraction spectra showed that the Cd2GeSe4 thin films had a strong (113) preferred orientation. The crystal structure was hexagonal with lattice constants a = 7.405 A and c = 36.24 A. The optical energy band gap for Cd2GeSe4 film measured at room temperature was about 1.65 eV. The charged carrier dynamical behavior of Cd2GeSe4 film was investigated using the photoinduced discharge characteristics (PIDC). The calculated values of the electron mobility and carrier concentration were 17.3 cm2/Vs and 2 X1023/cm3, respectively.
