Taming quantum interference: a route to high electrical conductance in carbon nanotube assemblies
Teresa Kulka, Agnieszka E. Lekawa-Raus, John S. Bulmer +6
Miniaturized electronics require lightweight conductors that maintain high conductance under demanding conditions. CNT networks are promising candidates, but their transport is gov…
Generation of an anomalous linearly dispersing spin-polarized band in Bi-based topological insulators
Matthias Kronseder, Thomas Mayer, Jan Minár +11
We report the generation of an anomalous linearly dispersing, spin-polarized band in Bi-based topological insulator (TI) thin films, induced by soft Ar-ion bombardment followed by…
Quantum Limits of Electronic Transport in Nanostructured Macroscopic Conductors
Agnieszka E. Lekawa-Raus, John S. Bulmer, Teresa Kulka +7
Macroscopic assemblies of one- and two-dimensional materials promise to translate nanoscale electronic properties into device-scale performance, yet the microscopic principles gove…
Transcendental momentum quantization in semiconducting Rashba nanowires and zero energy states in their normal and superconducting phase
Nico Leumer, Harald Schmid, Milena Grifoni +1
We study finite system properties of the canonical low energy model for a semiconducting nanowire with Rashba spin-orbit coupling. The case of an isolated wire as well as of one pr…
A universal route to chiral Ising superconductivity in monolayer TaS and NbSe
Lucia Gibelli, Simon Höcherl, Julian Siegl +4
We investigate Ising superconductivity in two archetypal intrinsic superconductors, monolayer 1H-TaS and 1H-NbSe, in a bottom-up approach. Using ab initio-based tight-bindi…
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;…
