Stable topological insulators achieved using high energy electron beams
Lukas Zhao, Marcin Konczykowski, Haiming Deng +9
Topological insulators are transformative quantum solids with immune-to-disorder metallic surface states having Dirac band structure. Ubiquitous charged bulk defects, however, pull…
Emergent surface superconductivity of nanosized Dirac puddles in a topological insulator
Lukas Zhao, Haiming Deng, Inna Korzhovska +8
Surfaces of three-dimensional topological insulators have emerged as one of the most remarkable states of condensed quantum matter1-5 where exotic electronic phases of Dirac partic…
Quantum Transport in Graphene Nanoribbons with Realistic Edges
Patrick Hawkins, Milan Begliarbekov, Marko Zivkovic +2
Due to their unique electrical properties, graphene nanoribbons (GNRs) show great promise as the building blocks of novel electronic devices. However, these properties are strongly…
Aperiodic conductivity oscillations in quasi-ballistic graphene heterojunctions
Milan Begliarbekov, Onejae Sul, Nan Ai +2
We observe conductivity oscillations with aperiodic spacing to only one side of the tunneling current in a dual-gated graphene field effect transistor with an n-p-n type potential…
Determination of Edge Purity in Bilayer Graphene Using micro-Raman Spectroscopy
Milan Begliarbekov, Onejae Sul, Sokratis Kalliakos +2
Polarization resolved micro-Raman spectroscopy was carried out at the edges of bilayer graphene. We find strong dependence of the intensity of the G band on the incident laser pola…
