further Meyer-Neldel Rule in a-Se₇₀Te₃₀-_xZn_x

摘要

Temperature dependence of conductivity is measured in dark as well as in presence of light in amorphous thin films of Se70Te30-xZnx in the temperature range 290 –365 K and in the intensity range 0-1190 Lux. We have investigated further Meyer Neldel rule by two different approaches. In first approach, the different sets of Meyer Neldel pre-factor ó00 and Meyer Neldel energy Emn are obtained by keeping composition constant. In the second approach, the different sets of Meyer Neldel prefactor ó00 and Meyer Neldel energy Emn are obtained by changing the composition. A strong correlation between Meyer Neldel pre-factor ó00 and Meyer Neldel energy Emn has been observed in both the cases.
