High Thermal Conductivity in Boron Arsenide: From Prediction to Reality

Boron arsenide has been recently predicted to be a new thermal conductor. In this Minireview, developments of boron arsenide growth techniques resulting in bigger and better crystals are discussed, and measurements of related properties, including thermal conductivity, are summarized.

Abstract

Modern first‐principles calculations predict that the thermal conductivity of boron arsenide is second only to that of diamond, the best thermal conductor, which may be of benefit for waste heat management in electronic devices. With the optimization of single‐crystal growth methods, large‐size and high‐quality boron arsenide single crystals have been grown and thermal conductivity measurements have verified the related predictions. Benefiting from the increased size and improved qualities, additional properties have been characterized. Important factors related to boron arsenide, remaining challenges, and the future outlook are addressed in this minireview.
