Optical Voltage Profiling of 2D Semiconductors via Proximal Exciton Sensing
Ha-Leem Kim, Hyungbin Lim, Yuanyi Yang +6
High contact resistances in atomically thin semiconductors often mask intrinsic electrical transport properties, particularly at low carrier densities where exotic correlated state…
Observation of two-component exciton condensates in an excitonic insulator
Ruishi Qi, Qize Li, Jiahui Nie +9
Macroscopic quantum coherence emerges when bosons condense into a Bose-Einstein condensate (BEC). First observed as a single-component superfluid in helium, BECs later emerged in u…
Observation of an exciton crystal in a moiré excitonic insulator
Ruishi Qi, Qize Li, Haleem Kim +9
Strong Coulomb interactions can drive electrons to crystallize into a Wigner lattice. Achieving the bosonic analogue - a crystal of excitons - has remained elusive due to their sho…
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…
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…
