Contactless cavity sensing of superfluid stiffness in atomically thin 4Hb-TaS
Trevor Chistolini, Ha-Leem Kim, Qiyu Wang +13
The exceptional tunability of two-dimensional van der Waals materials offers unique opportunities for exploring novel superconducting phases. However, in such systems, the measurem…
Terahertz electrodynamics in a zero-field Wigner crystal
Su-Di Chen, Ruishi Qi, Ha-Leem Kim +8
In clean two-dimensional (2D) systems, electrons are expected to self-organize into a regular lattice, a Wigner crystal, when their mutual Coulomb repulsion overwhelms kinetic ener…
Competition between excitonic insulators and quantum Hall states in correlated electron-hole bilayers
Ruishi Qi, Qize Li, Zuocheng Zhang +11
Excitonic insulators represent a unique quantum phase of matter, providing a rich ground for studying exotic quantum bosonic states. Strongly coupled electron-hole bilayers, which…
Direct measurement of terahertz conductivity in a gated monolayer semiconductor
Su-Di Chen, Qixin Feng, Wenyu Zhao +8
Two-dimensional semiconductors and their moiré superlattices have emerged as important platforms for investigating correlated electrons. However, many key properties of these syste…
Performance of Superconducting Resonators Suspended on SiN Membranes
Trevor Chistolini, Kyunghoon Lee, Archan Banerjee +8
Suspending devices on thin SiN membranes can limit their interaction with the bulk substrate and reduce parasitic capacitance to ground. While suspending devices on membranes is us…
Johnson-noise-limited cancellation-free microwave impedance microscopy with monolithic silicon cantilever probes
Jun-Yi Shan, Nathaniel Morrison, Su-Di Chen +2
Microwave impedance microscopy (MIM) is an emerging scanning probe technique for nanoscale complex permittivity mapping and has made significant impacts in diverse fields from semi…
Quantum Melting of a Disordered Wigner Solid
Ziyu Xiang, Hongyuan Li, Jianghan Xiao +15
The behavior of two-dimensional electron gas (2DEG) in extreme coupling limits are reasonably well-understood, but our understanding of intermediate region remains limited. Strongl…
Low Resistance Ohmic Contact to P-type Monolayer WSe2
Jingxu Xie, Zuocheng Zhang, Haodong Zhang +13
Advanced microelectronics in the future may require semiconducting channel materials beyond silicon. Two-dimensional (2D) semiconductors, characterized by their atomically thin thi…
Electrically controlled interlayer trion fluid in electron-hole bilayers
Ruishi Qi, Qize Li, Zuocheng Zhang +12
The combination of repulsive and attractive Coulomb interactions in a quantum electron(e)-hole(h) fluid can give rise to novel correlated phases of multiparticle charge complexes s…
Terahertz phonon engineering with van der Waals heterostructures
Yoseob Yoon, Zheyu Lu, Can Uzundal +11
Phononic engineering at gigahertz (GHz) frequencies form the foundation of microwave acoustic filters, acousto-optic modulators, and quantum transducers. Terahertz (THz) phononic e…
