2021年2月19日 · Single- and few-layer crystals of exfoliated MoTe2 have been characterized spectroscopically by photoluminescence, Raman scattering, and optical absorption measurements. We find that MoTe2 in the monolayer limit displays strong photoluminescence.

2018年6月1日 · 2H- and-phase monolayer MoTe 2 films on highly oriented pyrolytic graphite are studied using scanning tunneling microscopy and spectroscopy (STM/STS). The phase transition of MoTe 2 can be controlled by a post-growth annealing process, and the intermediate state during the phase transition is directly observed by STM.

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.

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.

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 …

2018年8月20日 · Here we report a Fourier transform scanning tunneling spectroscopy (FT-STS) study on a type-II Weyl semimetal candidate MoTe 2 whose Weyl points are predicated to be located above Fermi level.

2024年4月12日 · The local density of states arising from different types of defects was revealed by scanning tunneling spectroscopy (STS). To evaluate the macroscopic transport properties of corresponding samples while avoiding disturbing factors like oxidation and phase transition, the conductivity was investigated by measuring the current–voltage ( I – V ...

2018年4月1日 · Using the polymorphic heteroepitaxy, most recently coplanar semiconductor/metal (2H/1T′) few-layer MoTe 2 heterostructures were experimentally synthesized, highly promising to build circuit components for next generation nanoelectronics.

2022年7月16日 · In this paper, we investigate a single layer of 2H-MoTe2 grown on graphene by MBE and we present scanning tunneling microscopy (STM) investigations combined with density functional theory (DFT ...
