Experimental evidence for the third level (А+) of Hg vacancy in Hg1−xCdxTe

► Mercury vacancy in Hg1−xCdxTe is not a two-level, but a three-level acceptor. ► A third level (А+ state) appears due to a capture of hole by neutral vacancy. ► A positive space charge region (SCR) arises under radiation. ► This SCR causes the anomalies of photoelectromagnetic effect (PME) at T...
