ABSTRACT

Gas sensing performance of chemically deposited nanocrystalline Cu2S thin films

R. H. Bari

ABSTRACT

In this work, nanocrystalline Cu2S thin films have been prepared by spray pyrolysis technique. These films were characterized by different analytical instruments such as XRD, FE-SEM and EDAX to known crystal structure, surface morphology and elemental composition. Gas sensing performance of the prepared thin films was conducted using static gas sensing system and it was observed that prepared thin film sample S3 shows maximum gas response (S=560) to the H2S gas at operating temperature 150 0C with rapid response (4 s) and fast recovery (9 s) of the sensor. The results are discussed and interpreted. Keywords: Nanocrystalline d Cu2S thin films, spray pyrolysis, H2S gas sensor.
