(Department of Physics. College of Engineering. Graduate College. University of Illinois at UrbanaChampaign., 1970)Some new techniques have been used to study the physical properties of sulfur centers in silicon. These techniques make use of the effects of the sulfur centers on the depletion region properties of a reversebiased PN ...
