Chemisorbed CO2 molecules on ZnO nanowires (100 nm) surface leading towards enhanced piezoelectric voltage

Here, we have studied the behavior of ZnO based piezoelectric mechanical transducer in the presence of CO2. We have analyzed reduction-oxidation mechanism of CO2 gas on ZnO nanowire surface and studied its behavior for the enhancement piezoelectric output voltage. Rise in piezoelectric potential for various CO2 exposures time intervals from 30 min to 3 h has been observed. Chemiresistive behavior of CO2 modified ZnO nanowires, is being explained...
