Consistency between reflection M-EELS and optical spectroscopy measurements of the long-wavelength density response of BiSrCaCuO
Jin Chen, Xuefei Guo, Christian Boyd +11
The density fluctuation spectrum captures many fundamental properties of strange metals. Using momentum-resolved electron energy-loss spectroscopy (M-EELS), we recently showed that…
Influence of Structural Defects on Charge Density Waves in 1T-TaS2
I. Lutsyk, K. Szalowski, P. Krukowski +22
The influence of intrinsic defects of 1T-TaS2 on charge density waves (CDW) is studied using scanning tunneling microscopy and spectroscopy (STM, STS), angle-resolved photoelectron…
Dimensional crossover and symmetry transformation of the charge density waves in VSe2
P. Chen, Y. -H. Chan, R. -Y. Liu +5
Collective phenomena in solids can be sensitive to the dimensionality of the system; a case of special interest is VSe2, which shows a (r7 x r3) charge density wave (CDW) in the si…
Evidence of high-temperature exciton condensation in a two-dimensional semimetal
Qiang Gao, Yang-hao Chan, Yuzhe Wang +10
Electrons and holes can spontaneously form excitons and condense in a semimetal or semiconductor, as predicted decades ago. This type of Bose condensation can happen at much higher…
Edge States of α-Bismuthene Nanostructures
Sara Salehitaleghani, Tobias Maerkl, Pawel J Kowalczyk +5
We present a systematic investigation of the edge states of two-dimensional α-bismuthene (α-Bi) structures self-assembled on HOPG substrates, using scanning tunnelling microscopy a…
Anharmonic multiphonon origin of the valence plasmon in SrTi1-xNbxO3
Caitlin S. Kengle, Samantha I. Rubeck, Melinda Rak +10
Doped SrTi1-xNbxO3 exhibits superconductivity and a mid-infrared optical response reminiscent of copper-oxide superconductors. Strangely, its plasma frequency, omega_p, increases b…
