Quantum transport in graphene nanoribbons (GNRs): Electron-electron and electron-phonon interactions

Abstract

Graphene nanoribbons (GNRs) exhibit unique electronic properties that make them suitable for applications in nano-electronics. This study investigates quantum transport in GNRs, focusing on the impact of electron-electron and electron-phonon interactions on transport properties. Using the Non-Equilibrium Green’s Function (NEGF) formalism and a tight-binding approximation, we model electronic states and calculate the transmission function under varying conditions. Detailed results highlight the role of edge configurations, temperature dependence, and scattering mechanisms on carrier mobility, offering insights for optimizing GNR-based devices.
