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…
Orbital dependent Coulomb drag in electron-hole bilayer graphene heterostructures
Zuocheng Zhang, Ruishi Qi, Jingxu Xie +5
We report Coulomb drag studies in an electron-hole bilayer graphene heterostructure in a magnetic field, where the orbital, spin, and valley degrees of freedom are lifted by the co…
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…
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…
