摘要：
Ternary diluted magnetic semiconductors Cd1-xMnxTe obtained by Bridgman method in the range of composition 0less than or equal toxless than or equal to0.7 were investigated. The photoacoustic spectroscopy with a piezoelectric transducer was employed to evaluate the energy gaps of Cd1-xMnxTe bulk mixed crystals at room temperature. A linear increase of energy gap with increasing x value has been observed. Photoacoustic data were correlated with ellipsometric measurements. (C) 2003 American Institute of Physics.
