Abstract

We report fabrication and successful testing of a gas ionization sensor made of silver nanowires (AgNWs) sandwiched between two parallel plates. The device was tested in low pressure argon gas (0.1≤ P ≤0^-4 torr) where the breakdown voltages (V_b) were recorded against pressure. The new device displayed considerably lower V_b compared to its gold nanowire (AuNW)-based counterparts. The reduction of V_b was justified based on the increase in the secondary electron emission factor on AgNWs due to the lower workfunction of silver. We have also developed a simulation tool to model the device. Our model is based on combined Particle-In-Cell and Monte-Carlo-Collision (PIC-MCC) approaches which provides a platform for further development and optimization of the device.
