Description

Long-standing challenges to simultaneously accomplish crystal-like electrical transport and glass-like thermal transport in materials hinder the development of thermoelectric energy conversion technologies. We show that the unusual combination of these transport properties can be realized in electron-poor II−V semiconductor CdSb. Anisotropic multicenter bonding in CdSb is essential to both electrical and thermal transport. The electrondeficiency-sharing multicenter interactions lead to low...[Show more]
