Poole-frenkel Photoconductivity in Synthesized Cdse : Mn+2 Ions Thin Films

Abstract: CdSe semiconductors were synthesized with Mn+2 odd dopants from 1-9at.% onto ultrafine ITO glass substrates. Successive Ionic layer Adsorption and reaction (SILAR) technique was used in the synthesis. With proper fabrication of metal electrode contacts and 5mm inter electrode spacing across the films, photoconductivity was measured with a high input impedence (1014 Ω) electrometer amplifier under -108V-0-(+108)V in both polarity of applied bias and was found to obey two distinct conduction mechanisms – ohmic in low field and Poole - Frenkel type at high fields within the regions of the applied fields.
