RESUMO
Thin film Al/Sb2Pb1Se7/Al, MGM, sandwiched structures, prepared using thermal evaporation technique have been studied. The DC measurements at low electric field suggest that the electrical transport is governed by space charge limited conduction (SCLC) mechanism. The detailed analysis of current-voltage limited conduction (SCLC) mechanism characteristics on the basis of SCLC theory reveals the presence of uniformly distributed trap density of the order of 10(23) m-3 eV-1 with average activation energy 0.48 eV.
