FIG. 1.

(Color online) (a) Low-temperature (5 K) PL spectrum of CZT crystals. Upper inset is an optical micrograph of the investigated area, ∼6 × 9 μm2, showing a typical triangular-shaped Te inclusion. (b) Low-temperature spatially resolved micro-scale PL map of the position of the donor-bound-exciton (D0, X) peak at 1.664 eV. Region A and region B exhibit two areas with a large blue-shift in the photo energy of the (D0, X) peak.

FIG. 2.

(Color online) PL integrated intensity maps of different radiative transitions including (a) donor-bound- exciton (D0, X) peak at 1.664 eV; (b) DAP peak at 1.628 eV; and, (c) defect-related D band extending from 1.560–1.430 eV.

FIG. 3.

(Color online) PL maps of line width (FWHM) of different radiative transitions including (a) donor-bound-exciton (D0, X) peak at 1.664 eV; (b) DAP peak at 1.628 eV; and, (c) defect-related D band extending from 1.560–1.430 eV.
