Continuum models of the electrochemical diffuse layer in electronic-structure calculations (open access)

Continuum models of the electrochemical diffuse layer in electronic-structure calculations

This article presents a critical comparison of continuum diffuse-layer models that can be coupled to an atomistic first-principles description of the charged metal surface in order to account for the electrolyte screening at electrified interfaces.

Absorption and emission modulation in a MoS2–GaN (0001) heterostructure by interface phonon–exciton coupling (open access)

Absorption and emission modulation in a MoS2–GaN (0001) heterostructure by interface phonon–exciton coupling

Article reporting the change in the transient absorption characteristics of monolayer MoS2 and the modified PL emission characteristics in a monolayer MoS2–GaN (0001) heterostructure due to the coupling of carriers with the phonon modes and the energy exchange at the interface. The results demonstrate the relevance of interface coupling between the semiconductors for the development of optical and electronic applications.
