RESEARCH ON SEMICONDUCTING DIAMONDS.
Abstract
Research was performed to determine the inherent phenomena causing semiconductivity in diamonds, with special consideration for the rare natural type II-b material. In this work, resistivity and Hall coefficient have been carefully measured on several type II-b samples over the temperature range of 100K to 900K. The apparatus developed for these measurements is described. From these measurements, the activation energy of the principal acceptor level was determined for each specimen, and concentrations of donors and acceptors were deduced by a graphical method. The magnetoresistance and coefficient of magnetoresistance for one specimen in two orientations and at two temperatures are presented. Optical and electrical evidence of a polysynthetic twin structure is presented and discussed. (Author)
