Two stream diffusion of Hg into CdTe

The diffusion of Hg into CdTe has been studied, under saturated vapour pressure conditions, as a function of time at 300 and 350°C. The Hg concentration profiles showed two components at short and intermediate anneal times reverting to single component at long times, indicating that the diffusion of Hg in CdTe is rate limiting involving two stream diffusion.
