The anti-distortive polaron : an alternative mechanism for lattice-mediated charge trapping
Hamideh Hassani, Eric Bousquet, Xu He +2
Polarons can naturally form in materials from the interaction of extra charge carriers with the atomic lattice. Ubiquitous, they are central to various topics and phenomena such as…
