Thermal Transport Properties of Black Phosphorus: A Topical Review

ABSTRACT

Black phosphorus (BP) is a layered direct bandgap semiconductor. Few-layer BP, an emergent and promising two-dimensional semiconductor, has attracted increasing interest for novel electronic, photonic, and energy conversion applications due to its unique tunable direct bandgap and anisotropic in-plane transport properties. Understanding the thermal transport properties is critical for thermal management of electronics and thermoelectric applications. In this review, we cover the thermal transport properties of single-layer, few-layer, and bulk BP from most recent theoretical and experimental work, with a particular focus on the anisotropic in-plane thermal conductivity.
