Splitting of conductance resonance through a magnetic quantum dot in graphene
Nojoon Myoung, Jung-Wan Ryu, Hee Chul Park +2
We report a dual resonance feature in ballistic conductance through a quantum Hall graphene nanoribbon with a magnetic quantum dot. Such a magnetic quantum dot localizes Dirac ferm…
Gate-Tunable Spin Transport and Giant Electroresistance in Ferromagnetic Graphene Vertical Heterostructures
Nojoon Myoung, Hee Chul Park, Seung Joo Lee
We investigate spin transport through ferromagnetic graphene vertical heterostructures where a sandwiched tunneling layer is either a normal or ferroelectric insulator. We show tha…
Large Current Modulation and Spin-Dependent Tunneling of Vertical Graphene/MoS Heterostructures
Nojoon Myoung, Kyungchul Seo, Seung Joo Lee +1
Vertical graphene heterostructures have been introduced as an alternative architecture for electronic devices by using quantum tunneling. Here, we present that the current on/off r…
Gauged Monopole-Bubble
Yoonbai Kim, Seung Joo Lee, Kei-ichi Maeda +1
The decay of a metastable false vacuum by bubble nucleation is studied in the high temperature limit of the gauge theory in which an SO(3) gauge symmetry is spontaneously broken to…
