Abstract: | Abstract We report on activated capture and emission experiments obtained under hydrostatic pressure. The observed structures in the thermostimulated capture curves are interpreted as a competition between capture and emission from the different configurations of the DX center, which are related to the local environment of the Si atom. The analysis of the capture kinetic experiments supports the hypothesis of the negative charge state of the DX center. |
