Adjudicating Conduction Mechanisms in High Performance Carbon Nanotube Fibers
John Bulmer, Chris Kovacs, Thomas Bullard +15
The performance of carbon nanotube (CNT) cables, a contender for copper-wire replacement, is tied to its metallic and semi-conducting-like conductivity responses with temperature;…
Quantum oscillations of holes in GaN
Chuan F. C. Chang, Joseph E. Dill, Zexuan Zhang +12
GaN has emerged to be a major semiconductor akin to silicon due to its revolutionary impacts in solid state lighting, critically enabled by p-type doping, and high-performance radi…
Competing electronic ground states in the heavy-fermion superconductor CeRh2As2
Joanna BÅawat, Grzegorz Chajewski, Daniel Gnida +4
CeRh2As2 is rare among superconductors, in that magnetic field tunes it between two distinct superconducting phases. Combined with a lack of local inversion symmetry and an upper c…
Unconventional Magnetic Oscillations in Kagome Mott Insulators
Guoxin Zheng, Yuan Zhu, Kuan-Wen Chen +12
In metals, electrons in a magnetic field undergo cyclotron motion, leading to oscillations in physical properties called quantum oscillations. This phenomenon has never been seen i…
