Paper Title:
Fabrication and Characterization of Organic Semiconductor Based Gas Sensor
  Abstract

Thin films of organic semiconductor based azo-dye, OD 25, of the average thickness, 750 ± 10 nm, were desposited successfully on the glass substrate for gas sensing applications. Electrical conductivity was of the film as measured by impedance spectroscopy, showed an increase with frequency that was attributed to non-metallic nature of the film. Moreover, single conduction mechanism and negligible contact resistance showed good quality of the sensor film. Deposited film with Al and Ag electrodes showed good conductance when exposed to water and ethanol vapors.
