The difference in the peak temperatures of DLTS and C2-DLTS is discussed with reference to the measurement of deep levels in semiconductors. The emission rate of a trap level can be accurately determined when the peak temperature observed in DLTS agrees with that in C2-DLTS. When the peak temperatures disagree, the trap depth and trap density cannot be determined correctly, and the junction profile and trap density have a great effect on the peak temperatures of DLTS and C2-DLTS. These phenomena appear in DLTS and C2-DLTS measurements on Au-doped Si p+n diodes. It is necessary to use C2-DLTS together with DLTS in the study of deep impurities in semiconductors.
