Özet

The effective diffusion coefficients of Cu for thermal and photodiffusion in the CdTe films have been estimated from resistivity versus duration of thermal or photoannealing curves. In the temperature range 60-200degreesC the effective coefficient of thermal diffusion (D) and photodiffusion (D-ph) are described as D-t = 7.3 x 10(-7)exp(-0.33/kT) and D-ph = 4.7 x 10(-8)exp(-0.20/kT).
