TWO-ELECTRON IMPURITY CENTERS WITH NEGATIVE CORRELATION ENERGY
Abstract
Using the Messbauer spectroscopy method on the 119 Sn isotope, two-electron tin centers with negative correlation energy were identified. It was established that favorable conditions for exchange are realized in PbSe , since for this material the hole concentration is much higher than for PbS.
Keywords
Mixed centers, point defects, negative correlation energy
