Popis:	The diffusion of mercury in HgTe‐related materials has played a major role in the development of devices utilizing the unique features of this family of materials. The study of mercury diffusion, however, has been limited to diffusion perpendicular to the surface (i.e., into or out of the sample). We present evidence showing that when samples undergo laser annealing, substantial amounts of mercury are displaced laterally as well. This lateral diffusion was observed with the use of thermal probe mapping of slices of HgMnTe and HgCdTe.
