On the nature and charge state of the X-Defect, a radiation-induced Silicon defect with field-enhanced charge carrier emission

Niels Sorgenfrei, Yana Gurimskaya, Anja Himmerlich +4

The elusive X-Defect, a defect found in low-resistivity -type Silicon after irradiation, observed as a low-temperature shoulder of the $\mathrm{B}_\mathrm{i}\mathrm{O}_\mathrm{i…
