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…
Point contacts in encapsulated graphene
Clevin Handschin, Balint Fülöp, Péter Makk +6
We present a novel method to establish inner point contacts on hexagonal boron nitride (hBN) encapsulated graphene heterostructures with dimensions as small as 100 nm by pre-patter…
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…
Role of hexagonal boron nitride in protecting ferromagnetic nanostructures from oxidation
Simon Zihlmann, Péter Makk, C. A. F. Vaz +1
Ferromagnetic contacts are widely used to inject spin polarized currents into non-magnetic materials such as semiconductors or 2-dimensional materials like graphene. In these syste…
Magnetic field tuning and quantum interference in a Cooper pair splitter
G. Fülöp, F. Domínguez, S. d'Hollosy +8
Cooper pair splitting (CPS) is a process in which the electrons of naturally occurring spin-singlet pairs in a superconductor are spatially separated using two quantum dots. Here w…
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…
