Analysis
This paper investigates the linear exciton Hall and Nernst effects in monolayer 2D semiconductors. It uses semi-classical transport theory to derive the exciton Berry curvature and analyzes its impact on the Hall and Nernst currents. The study highlights the role of material symmetry in inducing these effects, even without Berry curvature, and provides insights into the behavior of excitons in specific materials like TMDs and black phosphorus. The findings are relevant for understanding and potentially manipulating exciton transport in 2D materials for optoelectronic applications.
