Principles of the optimum lock-in averageing in DLTS measurement

  • Published:
Acta Physica Academiae Scientiarum Hungaricae

Abstract

The advantages of the transient capacitance/current signal averageing by lock-in amplifier are emphasized: improved signal to noise ratio and better detectability of non exponential transients. The concept of rate window independent phase setting is introduced which overcomes the existing difficulties of the lock-in detection technique. Finally, details of a custom built DLTS apparatus are given.
