Direct measurement of ferroelectric polarization in a tunable semimetal
Sergio C. de la Barrera, Qingrui Cao, Yang Gao +7
Ferroelectricity, the electrostatic counterpart to ferromagnetism, has long been thought to be incompatible with metallicity due to screening of electric dipoles and external elect…
Charged bosons made of fermions in a solid state system without Cooper pairing
Z. Sun, J. Beaumariage, Q. Wan +9
We report experimental evidence for charged boson states in a solid without Cooper pairing, based on attaching two free carriers to an exciton in a semiconducting system. Theoretic…
Observation of the Interlayer Exciton Gases in WSe -p: WSe Heterostructures
Zheng Sun, Jonathan Beaumariage, Qingrui Cao +4
Interlayer excitons (IXs) possess a much longer lifetime than intralayer excitons due to the spatial separation of the electrons and holes; hence, they have been pursued to create…
