Electron Impact Ionization, Attachment, Drift Velocities and Longitudinal Diffusion of SCN2 at the Critical Point 127 K and 3.4 MPa

Abstract

The discharge mechanism of the supercritical nitrogen (SCN2) at the critical point 127 K and 3.4 MPa were discussed, and the key parameters showing the discharge behaviors of the SCN2 were calculated numerically by the BOLSIG+. Furthermore, the dynamical behaviors of the SCN2 clustering are carefully demonstrated by the molecule dynamics theory and some distinctively phenomena are discovered by the simulating calculation under the 50, 100, 150, 200, 250, 300, 350, 400, 450 and 500 Td. The results show that SCN2 is a promising new dielectric in the future.
