Electrically tunable spin qubits in strain-engineered graphene p-n junctions
Myung-Chul Jung, Nojoon Myoung
Strain engineering enables quantum confinement in pristine graphene without degrading its intrinsic mobility and spin coherence. Here, we extend previously proposed strain-induced…
Radio-Frequency Detection of Fabry-Pérot Interference and Quantum Capacitance in Long-Channel Three-Dimensional Dirac Semimetal Cd3As2 Nanowires
Sung Jin An, Jisu Kim, Myung-Chul Jung +10
We demonstrate phase-coherent transport in suspended long-channel Cd3As2 nanowire devices using both direct current (DC) transport and radio-frequency (RF) reflectometry measuremen…
Quantum-Hall Spectroscopy of Elliptically Deformed Graphene Nanobubble Qubits
Myung-Chul Jung, Nojoon Myoung
With recent advances in strain-engineering technology of graphene and 2D materials, graphene quantum dots (QDs) defined by the strain-induced pseudo-magnetic fields (PMFs) have bee…
Nanowrinkle Waveguide in Graphene for Enabling Secure Dirac Fermion Transport
Seunghyun Jun, Myung-Chul Jung, Nojoon Myoung
Localized states in graphene have garnered significant attention in quantum information science due to their potential applications. Despite graphene's superior transport and elect…
