ARPES and STM study on twisted transition metal dichalcogenides

ORAL

Abstract

Twisted van der Waals heterostructures have recently been proposed as a condensed-matter platform for realizing controllable quantum models due to the low-energy moiré bands with specific charge distributions in moiré superlattices. Here, using angle-resolved photoemission spectroscopy with sub-micron spatial resolution (μ-ARPES) and scanning tunneling microscopy (STM), we performed a systematic investigation on the electronic structure of twisted bilayer WSe2. Consistent evidence for moiré bands in both real and momentum space have been observed, which confirms twisted transition metal dichalcogenides as a versatile platform to investigate strongly correlated physics.
