Measuring the Electronic Bandgap of Carbon Nanotube Networks in Non-ideal p-n Diodes
Gideon Oyibo, Thomas Barrett, Sharadh Jois +2
The measurement of the bandgap in quasi-one dimensional materials such as carbon nanotubes is challenging due to its dimensionality. In this work, we measure the electronic bandgap…
All-carbon nanotube solar cell devices mimic photosynthesis
Gideon Oyibo, Thomas Barrett, Sharadh Jois +2
Photovoltaics has two main processes: Optical absorption and power conversion. In photosynthesis, the two equivalent processes are optical absorption and chemical conversion. Where…
Andreev Reflection and Klein Tunneling in High-Temperature Superconductor/Graphene Junctions
Sharadh Jois, Jose L. Lado, Genda Gu +2
Scattering processes in quantum materials emerge as resonances in electronic transport, including confined modes, Andreev states, and Yu-Shiba-Rusinov states. However, in most inst…
Geometric interference in a high-mobility graphene annulus p-n junction device
Son T. Le, Albert F. Rigosi, Joseph A. Hagmann +3
The emergence of interference is observed in the resistance of a graphene annulus pn junction device as a result of applying two separate gate voltages. The observed resistance pat…
Scalable Gate-Defined Majorana Fermions in 2D p-Wave Superconductors
Ji Ung Lee
We provide a conceptual framework for developing a scalable topological quantum computer. It relies on forming Majorana fermions using circular electronic gates in two-dimensional…
Strong equilibration of Landau levels edge-states at the graphene edge
Son T. Le, Joseph A. Hagmann, Nikolai Klimov +4
We present the results of an experimental study of the interaction of quantized Landau level (LL) edge-states at the physical edge of graphene by using a graphene pn junction devic…
