Contacts with semi-insulators
Abstract
A review is given of studies of effects associated with contacts to semiinsulators. Previous investigations of contact effects in semiconductors are discussed with emphasis on the process of minority-carrier injection. Van Roosbroeck's (1970) model of minority-carrier injection into semiinsulators is outlined, and it is shown that this process results in majority-carrier depletion and lower than normal resistances in poorly conducting materials. Models that yield higher than normal resistances are considered, and it is noted that for such models to be realistic, trapping processes must be taken into account.
