Abstract
Diluted magnetic semiconductor Cd1âxFexS (0 < x < 0.4) films were grown by the low-pressure metal organic chemical vapor deposition on c-Al2O3 substrates. All the films were fabricated at 633 K under a hydrogen pressure of 104 Pa. Structure and composition analysis revealed that the Fe was alloyed into the lattice structure of CdS, forming solid solution instead of precipitation. The room temperature optical band gap of Cd1âxFexS films can be tuned from 2.454 to 2.310 eV with increasing Fe concentration from x = 0 to 0.37. A typical Van Vleck-type paramagnetism of Cd0.88Fe0.12S film was observed using superconduction quantum interference device magnetometer below 6 K.
