Semiconductor Material Evaluation by Means of Schottky Contacts

  • Klaus Heime
Part of the NATO Advanced Study Institutes Series book series (NSSB, volume 46)


The large variety of possible application of semiconductor devices — from high current, high voltage to microwave devices, from integrated optoelectronics — is to a large extent due to the fact that semiconductors can be doped to a desired type and magnitude of conductivity. This is done by incorporating impurities whose energy levels in the forbidden gap are close to valence or conduction band and which are therefore completely ionized at normal temperatures of device operation. These levels are called shallow levels. The first part of this paper will discuss the principal methods for the evaluation of the concentration and local distribution of these shallow levels by means of Schottky contacts.
