The electronic structure of nanoscale interfaces

Pages 850-860 | Received 31 Dec 2016, Accepted 27 Mar 2017, Published online: 04 May 2017
 

Abstract

We review approaches to determining the electronic structure and orbital level alignment at nanoscale interfaces. Errors introduced by common exchange–correlation functionals used in Kohn–Sham density functional theory are discussed. We discuss level alignment results based on many-body perturbation theory within the GW approximation, and highlight the technical challenges and solutions faced when applying this approach to nanoscale interfaces.
