Electrical Probing of Dark Excitons through Microwave Permittivity
Alex Stram, Zhida Liu, Ziheng Zhang +17
Excitons in atomically thin semiconductors are almost always probed through their optical signatures, because the short lifetimes of these transient quasiparticles are generally as…
Atomistic Control in Molecular Beam Epitaxy Growth of Intrinsic Magnetic Topological Insulator MnBi2Te4
Hyunsue Kim, Mengke Liu, Lisa Frammolino +13
Intrinsic magnetic topological insulators have emerged as a promising platform to study the interplay between topological surface states and ferromagnetism. This unique interplay c…
Creating a Nanoscale Lateral Heterojunction in a Semiconductor Monolayer with a Large Built-in Potential
Madisen Holbrook, Yuxuan Chen, Hyunsue Kim +6
The ability to engineer atomically thin nanoscale lateral heterojunctions (HJs) is critical to lay the foundation for future two-dimensional (2D) device technology. However, the tr…
Visualizing the interplay of Dirac mass gap and magnetism at nanoscale in intrinsic magnetic topological insulators
Mengke Liu, Chao Lei, Hyunsue Kim +5
In intrinsic magnetic topological insulators, Dirac surface state gaps are prerequisites for quantum anomalous Hall and axion insulating states. Unambiguous experimental identifica…
