Surface versus Bulk: Charge Carriers Play by Different Rules

Abstract

In this issue of Chem, El-Zohry et al. employ a novel time-resolved electron microscopy technique to report that photoinduced charge-carrier diffusion on a semiconducting cadmium telluride single-crystal surface exhibits unusual features that are not only distinct from those of the bulk crystal but also considerably dependent on the crystal facet orientation. © 2019 Elsevier Inc.In this issue of Chem, El-Zohry et al. employ a novel time-resolved electron microscopy technique to report that photoinduced charge-carrier diffusion on a semiconducting cadmium telluride single-crystal surface exhibits unusual features that are not only distinct from those of the bulk crystal but also considerably dependent on the crystal facet orientation.
