Two phase transitions driven by surface electron-doping in WTe
Antonio Rossi, Giacomo Resta, Seng Huat Lee +6
WTe is a multifunctional quantum material exhibiting numerous emergent phases in which tuning of the carrier density plays an important role. Here we demonstrate two non-monoto…
Direct evidence for efficient ultrafast charge separation in epitaxial WS/graphene heterostructure
S. Aeschlimann, A. Rossi, M. Chávez-Cervantes +8
We use time- and angle-resolved photoemission spectroscopy (tr-ARPES) to investigate ultrafast charge transfer in an epitaxial heterostructure made of monolayer WS and graphene…
Superlubricity of epitaxial monolayer WS2 on graphene
Holger Buech, Antonio Rossi, Stiven Forti +3
We report on the superlubric sliding of monolayer tungsten disulfide (WS2) on epitaxial graphene (EG) on silicon carbide (SiC). WS2 single-crystalline flakes with lateral size of h…
Li-intercalated Graphene on SiC(0001): an STM study
Sara Fiori, Yuya Murata, Stefano Veronesi +3
We present a systematical study via scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED) on the effect of the exposure of Lithium (Li) on graphene on sili…
