 The study reports a new type of MoT2 monolayer called CT, MoT2, which has been constructed by introducing mirror-twin boundaries into a pristine monolayer via molecular beam epitaxy. Low-temperature scanning tunneling microscopy and spectroscopy, STM-STS, together with theoretical calculations revealed that the monolayer has an electronic Janus lattice, an energy-dependent atomic lattice, and a T-epsudosub lattice. The study identifies two broad and two prominent peaks in STS spectra corresponding to Dirac-like and flat electronic bands inherently existing in the CT lattice, and verifies these findings with density-functional theory calculations. Additionally, two types of intrinsic domain boundaries were observed, one of which maintains the electronic Janus lattice feature, suggesting potential applications as an energy-tunable electron tunneling barrier in future functional devices.
