Abstract

The establishment of an electrical contact to amorphous silicon nanoparticles was studied. The temperature-dependent I-V behavior of different electrode pair MSM devices were studied, to investigate the transport mechanism of the silicon particles. It was shown that the space charge limited current (SCLC) model fits the medium voltage range (2-6 V), while space charged limited current with Frenkel-Poole effect fits the ralatively high voltage range (5-8 V). Based on SCLC enhanced with Frenkel-Poole effect, the activation energy measured at high voltage was determined to 0.44 eV.
