band-edge electronic structure including defect formation and levels in As-doped HgCdTe for different annealing conditions as determined from our measurements. Dⁱ (i = d1, d2, and d3) represent deep levels. Color arrows depict a dynamic process that D^d1 can be de-complicated to D^d2 and D^d3, and further from D^d2 to D^d3 with temperature increasing.
