Valley separation via trigonal warping
Samuel Bladwell
Monolayer Graphene contains two inequivalent local minimum, valleys, located at and in the Brillouin zone. There has been considerable interest in the use of these two val…
Measuring hole g-factor anisotropies using transverse magnetic focusing
Samuel Bladwell, Oleg Sushkov
Recent theoretical and experimental results from quasi-one dimensional heavy hole systems have suggested that heavy hole gases have a strongly anisotropic g factor. In this theoret…
A quantum point contact as a (near) perfect spin polariser
Samuel Bladwell
In this paper, I present a simple method of obtaining spin-polarised current from a QPC with a large Rashba interaction. The origin of this spin polarisation is the adiabatic evolu…
Interference in spin-orbit coupled transverse magnetic focusing; emergent phase due to in-plane magnetic fields
Samuel S. R. Bladwell, Oleg P. Sushkov
Spin-orbit (SO) interactions in two dimensional systems split the Fermi surface, and allow for the spatial separation of spin-states via transverse magnetic focusing (TMF). In this…
