Detecting crossed Andreev reflection in a quantum Hall interferometer with a superconducting beam splitter
Maxime Jamotte, Tom Menei, Manohar Kumar +2
We study time-domain electron interferometry in a Hong-Ou-Mandel (HOM) geometry, where a thin superconductor between two quantum Hall systems acts as the beam splitter. By comparin…
Landau-Level-Resolved Mode Mixing and Shot Noise in Gate-Defined Graphene Quantum Point Contacts
Shakthidhar Vilvanathan, Jerin Saji, Kristiana Frei +2
Graphene quantum point contacts (QPCs) in the quantum Hall regime host competing transport mechanisms including chiral edge propagation, valley degeneracy, and gate-induced mode mi…
Defects in h-BN tunnel barrier for local electrostatic probing of two dimensional materials
Ying Liu, Zhenbing Tan, Manohar Kumar +3
Defects in hexagonal boron nitride (h-BN) layer can facilitate tunneling current through thick h-BN tunneling barriers. We have investigated such current-mediating defects as local…
Breakdown of zero-energy quantum Hall state in graphene in the light of current fluctuations and shot noise
Antti Laitinen, Manohar Kumar, Teemu Elo +3
We have investigated the cross-over from Zener tunneling of single charge carriers to avalanche type of bunched electron transport in a suspended graphene Corbino disk in the zerot…
