2019年4月16日 · Here, by combining first-principles calculations and experimental studies, we report on the discovery of robust room-temperature out-of-plane ferroelectricity which is realized in the thinnest...

2022年7月16日 · In this paper, we investigate a single layer of 2 H -MoTe 2 grown on graphene by MBE and we present scanning tunneling microscopy (STM) investigations combined with density functional theory...

2023年10月9日 · Low-temperature scanning tunneling microscopy and spectroscopy (STM/STS) together with theoretical calculations reveal that the monolayer has an electronic Janus lattice, i.e., an...

1996年5月15日 · To get a better understanding of the STM images of TMD surfaces we investigated c~-MoTe2, /3- MoTe2 and WTe2(001) surfaces by AFM and STM. c~- and /3-MoTe2 have been chosen because of their chemically identical but structurally different nature [6,7].

2023年8月25日 · A thermally driven phase transition from Mo6Te6 nanowires to 1T′-MoTe2 films, grown on SrTiO3(001) surface by the molecular beam epitaxial methods, is demonstrated. A combined study of scanning tunneling microscopy/spectroscopy, electrical transport and magnetization measurements indicates the $T_{\mathrm{c}}$ of MoTe2 film is around 30&nbsp ...

2017年5月1日 · Here, we report molecular beam epitaxy growth of continuous molybdenum ditelluride (MoTe2) films on graphene substrates with good stoichiometry in both 2H and 1T′ phases. Post-growth annealing reveal phase transition suppressed in Te-rich atmosphere, through in-situ scanning tunneling microscopy/spectroscopy and X …

2023年12月19日 · Here, we demonstrate the epitaxial growth of 1T'-MoTe 2 on Au (111) and graphitized silicon carbide (Gr/SiC) by molecular beam epitaxy (MBE). We investigated the morphology of the grown 1T'-MoTe 2 at the atomic level by scanning tunnelling microscopy (STM) and revealed the corresponding microscopic growth mechanism.

2024年6月27日 · Here, we present scanning tunneling microscopy and spectroscopy (STM/STS) studies of the tMoTe2 moiré superlattice, with twist angles ranging from about 2.3° to 2.8°. We developed a contact-STM mode to apply pressure on tMoTe2 and observed a phase transition from band insulator to metal of tMoTe2 under pressure at the charge neutrality point.

2020年6月24日 · Here, for the first time, we observed atomic-scale structures of the charge distribution within one period in MTB of monolayer MoTe 2 by using scanning tunneling microscopy/spectroscopy. The coexisting apparent periodic lattice distortions and U-shaped energy gap clearly demonstrate a Peierls-type charge density wave (CDW).

Micro-focused angle-resolved photoemission spectroscopy (μ-ARPES) and low-temperature scanning tunneling microscopy (STM) in collaboration with first-principles band-structure calculations have revealed that this new 1T-MoTe 2 phase is realized by the band reconstruction due to the moiré potential formed between MoTe 2 and BL-graphene.
