Enhanced Superconductivity and Vortex Dynamics in One-Dimensional TaS2 Nanowires
Mathew Pollard, Visakha Ho, Clarissa Wisner +2
We report the synthesis of high-quality 2H-TaS2 nanowires via a controlled two-step conversion process from TaS3 precursors, achieving robust superconductivity with a transition te…
-vestigial nematic order due to superconducting fluctuations in the doped topological insulator NbBiSe and CuBiSe
Chang-woo Cho, Junying Shen, Jian Lyu +10
A state of matter with a multi-component order parameter can give rise to vestigial order. In the vestigial phase, the primary order is only partially melted, leaving a remaining s…
Scanning tunneling spectroscopy investigations of superconducting-doped topological insulators: Experimental pitfalls and results
Stefan Wilfert, Paolo Sessi, Zhiwei Wang +8
Recently the doping of topological insulators has attracted significant interest as a potential route towards topological superconductivity. Because many experimental techniques la…
Nematic topological superconducting phase in Nb-doped Bi2Se3
Junying Shen, Wen-Yu He, Noah Fan Qi Yuan +6
A nematic topological superconductor has an order parameter symmetry, which spontaneously breaks the crystalline symmetry in its superconducting state. This state can be observed,…
An increase in under hydrostatic pressure in the superconducting doped topological insulator NbBiSe
M. P. Smylie, K. Willa, K. Ryan +5
We report an unexpected positive hydrostatic pressure derivative of the superconducting transition temperature in the doped topological insulator \NBS via SQUID magnetometry i…
Andreev Reflection Spectroscopy of Topological Superconductor Candidate NbBiSe
Cihan Kurter, Aaron Finck, Erik Huemiller +10
We study unconventional superconductivity in thin exfoliated single crystals of a promising 3D topological superconductor candidate, Nb-doped BiSe through Andreev reflectio…
