Temperature and Magnetic Field Effects on the Conductivity Behavior in Two-Dimensional Electronic Systems

Abstract

The electrical conductivity in two-dimensional (2D) electronic systems is strongly influenced by temperature and applied magnetic fields. Beyond the classical Drude description, quantum effects such as weak localization (WL), anti-weak localization (AWL), and electron-electron interactions (EEI) significantly modify the conductivity at low temperatures. This work analyzes the combined impact of magnetic field and temperature on longitudinal conductivity in 2D systems, highlighting the underlying mechanisms and corresponding quantum corrections. The study demonstrates that magnetic field and temperature act as complementary probes for quantum corrections in 2D transport.
