Query: Quantum Confined Tomonaga-Luttinger Liquid in MoSe2 Twin Domain
  Boundaries   There have been conflicting reports on the electronic properties of twin
domain boundaries (DBs) in MoSe2 monolayer, including the quantum well states,
charge density wave, and Tomonaga-Luttinger liquid (TLL). Here we employ
low-temperature scanning tunneling spectroscopy to reveal both the quantum
confinement effect and signatures of TLL in the one-dimensional DBs. The data
do not support the CDW at temperatures down to ~5 K.
