Ballistic transport in nanodevices based on single-crystalline Cu thin films

Yongjin Cho, Su Jae Kim, Su Jae Kim, Min‐Hyoung Jung et autres

In ballistic transport, the movement of charged carriers remains unimpeded by scattering events. In this limit, microscopic parameters such as crystal momentum, spin and quantum phase are well conserved, allowing electrons to maintain their quantum coherence over longer distances. Nanoscale materials, such …

Twisted van der Waals Josephson Junction Based on a High- T c Superconductor

Jongyun Lee, Wonjun Lee, Gi‐Yeop Kim, Yong-Bin Choi et autres

Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other show versatility for studying exotic quantum phenomena. In particular, anisotropic layered materials have great potential for such twistronics applications, providing high tunability. Here, we report anisotropic superconducting order parameters …

Characterization of Shapiro steps in the presence of a 4π-periodic Josephson current

Jinho Park, Yong-Bin Choi, Gil‐Ho Lee, Hu-Jong Lee

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 explore fundamental physics such as non-Abelian statistics, as well as fault-tolerant quantum computation. Period doubling of …

Engineering Crossed Andreev Reflection in Double-Bilayer Graphene

Geon-Hyoung Park, Kenji Watanabe, Takashi Taniguchi, Gil‐Ho Lee et autres

Crossed Andreev reflection (CAR) is a nonlocal process that converts an incoming electron (hole) from one normal electrode to an out-going hole (electron) in another normal electrode through a supe...

Robust subgap edge conduction in bilayer graphene with disordered edge termination

Hyun‐Woo Lee, Kenji Watanabe, Takashi Taniguchi, Gil‐Ho Lee et autres

The subgap transport in electrostatically gapped bilayer graphene (BLG) is explored by adopting ultrashort constrictions of BLG. We confirmed the emergence of the edge conducting channels, with a residual conductance of $\ensuremath{\sim}2{e}^{2}/h$ per edge of realistic disorder. Transport along the edge state …

Engineering Crossed Andreev Reflection in Double-Bilayer Graphene

Geon-Hyoung Park, Kenji Watanabe, Takashi Taniguchi, Gil‐Ho Lee et autres

Crossed Andreev reflection (CAR) is a nonlocal process that converts an incoming electron (hole) from one normal electrode to an out-going hole (electron) in another normal electrode through a superconductor (SC). CAR corresponds to the inverse process of Cooper pair splitting, which …
