Vertical Nb Josephson junctions fabricated by direct metal deposition on both surfaces of freestanding graphene layers
Yoonkang Kim, Seongbeom Kim, Jeonglyul Kim +6
Vertical integration of superconducting electronics requires fabrication strategies that preserve pristine interfaces while accommodating oxidation-sensitive elemental superconduct…
Interface-Bound States and Majorana Zero Modes in Lateral Heterostructures of BiSe and SbTe with Proximity-Induced Superconductivity
Yoonkang Kim
We present a comprehensive investigation into the emergence of interface-bound states, particularly Majorana zero modes (MZMs), in a lateral heterostructure composed of two three-d…
Topological Surface States of 3D Topological Insulator on Twisted Bilayer Graphene
Yoonkang Kim
We present a comprehensive theoretical study of the topological surface states (TSS) of BiSe, a 3D topological insulator, epitaxially grown on twisted bilayer graphene (tBG…
Stochastic resonance in Schmitt trigger and its application towards weak signal detection
Yoonkang Kim, Donghyeok Seo
This study explores stochastic resonance (SR) in a Schmitt trigger circuit and its application to weak signal detection. SR, a phenomenon where noise synchronizes with weak signals…
