Goos-Hänchen-like shifts at metal/superconductor interface
Ying Liu, Zhi-Ming Yu, Hua Jiang +1
At a normal-metal/superconductor interface, an incident electron from the normal-metal (N) side can be normally reflected as an electron or Andreev reflected as a hole. We show tha…
Breakdown of zero-energy quantum Hall state in graphene in the light of current fluctuations and shot noise
Antti Laitinen, Manohar Kumar, Teemu Elo +3
We have investigated the cross-over from Zener tunneling of single charge carriers to avalanche type of bunched electron transport in a suspended graphene Corbino disk in the zerot…
Vortex crossing, trapping and pinning in superconducting nanowires of a NbSe two-dimensional crystal
Shaun A. Mills, Jacob J. Wisser, Chenyi Shen +2
Nanowires of two-dimensional (2D) crystals of type-II superconductor NbSe prepared by electron-beam lithography were studied, focusing on the effect of the motion of Abrikosov…
Superconductivity in single-layer films of FeSe with a transition temperature above 100 K
Jian-Feng Ge, Zhi-Long Liu, Canhua Liu +5
Recently, interface has been employed to enhance superconductivity in the single-layer FeSe films grown on SrTiO3(001)(STO) with a possible Tc of ~ 80 K, which is nearly ten times…
Structural and metal-insulator transitions in ionic liquid-gated Ca3Ru2O7 surface
Conor P. Puls, Xinxin Cai, Yuhe Zhang +3
We report the fabrication and measurements of ionic liquid gated Hall bar devices prepared on thin CaRuO flakes exfoliated from bulk single crystals that were grown by…
Single-crystal superconducting nanowires of NbSe fabricated by reactive plasma etching
Shaun A. Mills, Neal E. Staley, Jacob J. Wisser +3
We present the preparation and measurements of nanowires of single-crystal NbSe. These nanowires were prepared on ultrathin () flakes of NbSe mechanic…
