Abstracts/Announcement
The authors of this CRC 951 research highlight experimentally observed that the amount of ground-state charge transfer in a van der Waals (vdW) heterostructure increases by a factor of 3 when going from 7 K to room temperature. State-of-the-art electronic structure calculations of the full heterostructure reveal intracomponent electron–phonon coupling and inter-component electronic coupling as the key factors determining the amount of charge transfer.
