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…
