On the project

Replacing the external heater by self-heating effect increases the power efficiency of the gas sensor. We will measure electrical properties of nanowires with minimum self-heating (low current, pulse measurement, external heater) and in self-heating mod (higher current, self-heating by joule heat). This will enable us to use self-heating to control the nanowire temperature and help us understand factors influencing oxygen adsorption and the formation of the surface depletion layer on those nanowires, which plays crucial role in gas sensing.
