Towards Utilizing Scanning Gate Microscopy as a High-Resolution Probe of Valley Splitting in Si/SiGe Heterostructures
Efe Cakar, H. Ekmel Ercan, Gordian Fuchs +4
A detailed understanding of the material properties that affect the splitting between the two low-lying valley states in Si/SiGe heterostructures will be increasingly important as…

Thermopower in hBN/graphene/hBN superlattices
Victor H. Guarochico-Moreira, Christopher R. Anderson, Vladimir Fal'ko +9
Thermoelectric effects are highly sensitive to the asymmetry in the density of states around the Fermi energy and can be exploited as probes of the electronic structure. We experim…

Exploring room temperature spin transport under band gap opening in bilayer graphene
Christopher R. Anderson, Noel Natera-Cordero, Victor H. Guarochico-Moreira +2
We study the room-temperature electrical control of charge and spin transport in high-quality bilayer graphene, fully encapsulated with hBN and contacted via 1D spin injectors. We…
