Gate tuneable beamsplitter in ballistic graphene
Peter Rickhaus, Péter Makk, Ming-Hao Liu +2
We present a beam splitter in a suspended, ballistic, multiterminal, bilayer graphene device. By using local bottomgates, a p-n interface tilted with respect to the current directi…
Guiding of Electrons in a Few Mode Ballistic Graphene Channel
Peter Rickhaus, Ming-Hao Liu, Péter Makk +6
In graphene, the extremely fast charge carriers can be controlled by electron-optical elements, such as waveguides, in which the transmissivity is tuned by the wavelength. In this…
Snake Trajectories in Ultraclean Graphene p-n Junctions
Peter Rickhaus, Péter Makk, Ming-Hao Liu +5
Snake states are trajectories of charge carriers curving back and forth along an interface. There are two types of snake states, formed by either inverting the magnetic field direc…
