Electron-Electron Interactions in Device Simulation via Non-equilibrium Green's Functions and the GW Approximation
Leonard Deuschle, Jiang Cao, Alexandros Nikolaos Ziogas +4
The continuous scaling of metal-oxide-semiconductor field-effect transistors (MOSFETs) has led to device geometries where charged carriers are increasingly confined to ever smaller…
