Ballistic transport in nanodevices based on single-crystalline Cu thin film
Yongjin Cho, Su Jae Kim, Min-Hyoung Jung +7
In ballistic transport, the movement of charged carriers is essentially unimpeded by scattering events. In this limit, microscopic parameters such as crystal momentum, spin and qua…
Twisted van der Waals Josephson junction based on high-Tc superconductor
Jongyun Lee, Wonjun Lee, Gi-Yeop Kim +8
Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other show versatility for the study of exotic quantum phenomena. Especially, anisotropic layere…
Characterization of Shapiro steps in the presence of a 4π-periodic Josephson current
Jinho Park, Yong-Bin Choi, Gil-Ho Lee +1
The Majorana zero-energy modes (MZMs) residing at the boundary of topological superconductors have attracted a great deal of interest recently, as they provide a platform to explor…
Evidence of Higher Order Topology in Multilayer WTe from Josephson Coupling through Anisotropic Hinge States
Yong-Bin Choi, Yingming Xie, Chui-Zhen Chen +12
The noncentrosymmetric Td-WTe, previously known as a type-II Weyl semimetal, is expected to have higher order topological phases with topologically protected, helical one-dimen…
Short Ballistic Josephson Coupling in Planar Graphene Junctions with Inhomogeneous Carrier Doping
Jinho Park, Jae Hyeong Lee, Gil-Ho Lee +5
We report on short ballistic (SB) Josephson coupling in junctions embedded in a planar heterostructure of graphene. Ballistic Josephson coupling is confirmed by the Fabry-Perot-typ…
Proximity coupling in superconductor-graphene heterostructures
Gil-Ho Lee, Hu-Jong Lee
This review discusses the electronic properties and the prospective research directions of superconductor-graphene heterostructures. The basic electronic properties of graphene are…
