On-chip superconducting GHz RF reflectometry of the capacitance response in bilayer graphene
Sung Jin An, Minseo Cho, Minjun Park +12
In dual-gated bilayer graphene, a perpendicular displacement field opens a band gap that modifies both the channel conductance and the electronic compressibility, motivating measur…
Quantized Conductance through Surface States in High Quality Three-Dimensional Dirac Semimetal CdAs Nanowire/Nanoribbon p-n Junctions
Sungjin An, Zhuo Bin Siu, Vardan Kaladzhyan +8
We report the observation of quantized conductance in high-mobility three-dimensional Dirac semimetal CdAs nanowire and nanoribbon p-n junctions. By employing suspended dev…
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…
Enhanced Magnetization by Defect-Assisted Exciton Recombination in Atomically Thin CrCl
Xin-Yue Zhang, Thomas K. M. Graham, Hyeonhu Bae +14
Two dimensional (2D) semiconductors present unique opportunities to intertwine optical and magnetic functionalities and to tune these performances through defects and dopants. Here…
