We r.por. on the obs.r.ation of Meyer.neldel r.le in glas.y s.75Ge20Ag5 alloy wher. AE is.var.ed by two differ.nt methods. In the fir.t appr.ach, the intens.ty of light var.es.while meas.r.ng the photoconductivity in amor.hous.thin films.of s.75Ge20Ag5 ins.ead of changing compos.tion of the glas.y s.s.em. In the s.cond appr.ach, the var.ation of ac conductivity with temper.tur. is.found to be exponential and the activation ener.y is.found to var. with fr.quency.
