The vacancy-dopant complex in Silicon, often referred to as the E-center, is a well-known defect. In this study, we investigated vacancy complexes with three common dopants namely the Sb, P and As by measuring isochronal annealing profiles of all three E centres in n-type silicon.
Si doped with P and combinations of P with Sb and As were exposed to alpha radiation from an Am-241 source. By making use of high-resolution Laplace deep-level transient spectroscopy, we were able to distinguish the different E-centers from each other, and measure their annealing rates individually. Since the Schottky contacts degraded with temperature, a novel approach was taken, where annealings were done with the Schottky contacts replaced after each annealing.
