Nuclear-induced dephasing and signatures of hyperfine effects in isotopically purified C graphene
Vincent Strenzke, Jana M. Meyer, Isabell Grandt-Ionita +6
The hyperfine interaction between the spins of electrons and nuclei is both a blessing and a curse. It can provide a wealth of information when used as an experimental probing tech…
Resonantly hybridised excitons in moiré superlattices in van der Waals heterostructures
Evgeny M. Alexeev, David A. Ruiz-Tijerina, Mark Danovich +16
Atomically-thin layers of two-dimensional materials can be assembled in vertical stacks held together by relatively weak van der Waals forces, allowing for coupling between monolay…
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…
Electrical Modulation of Superconducting Critical Temperature in Liquid-Gated Thin Niobium Films
Jiman Choi, Pradheesh R., Hyungsang Kim +3
We demonstrate that the superconducting critical temperature (Tc) of thin niobium films can be electrically modulated in a liquid-gated geometry device. Tc can be suppressed and en…
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…
