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 …

The Korean government has focused on universities or colleges as the main targets of its
startup policy since the 2010s. However, the performance is not so good, with a low survival …

We have observed the zero-crossing steps in a surface junction of a mesa structure
microfabricated on the surface of a Bi 2 Sr 2 CaCu 2 O 8+ δ single crystal. With the …

We present a study of the critical currents of small sized intrinsic Josephson junction stacks
in external magnetic fields applied parallel to the CuO 2 layers. The stacks consisting of 5 …

Current-voltage curves of small area hysteretic intrinsic Josephson junctions, for which the
Josephson energy EJ= ħ J c/2 e is of the order of thermal energy k T, are investigated. A …

We report on two types of experiments with intrinsic Josephson systems made from layered
high-T c superconductors which show clear evidence of nonequilibirum effects.(1) In two …

Intrinsic Josephson junctions on Bi 2 Sr 2 CaCu 2 O 8+ δ superconductors are fabricated
using an in situ low-temperature cleavage technique, which allows for the fabrication of well …
