2020年5月8日 · Low electron energy diffraction (LEED) and scanning tunneling microscopy (STM) results reveal the existence of a well-ordered alloy monolayer characterized by (√3 × √3)R30° superstructure, while the x-ray photoemission spectroscopy (XPS) measurements indicate the presence of single chemical environment of the Te atoms associated with the ...

2020年1月1日 · Based on this monolayer Cu 2 Te structure model, we simulate an STM image (Fig. 2 (f)), which presents all the features in experimental STM image very well. We unveil the configuration of monolayer Cu 2 Te at atomic scale for the first time.

2021年1月26日 · Here we show that a single layer of hexagonal Cu 2 Te crystal could be synthesized by one-step liquid–solid interface growth and exfoliation. Characterizations of atomically resolved scanning tunneling microscope reveal that the Cu 2 Te monolayer consists of two lattice-matched distinct phases, similar to the 1T and 1T′ phases of MX 2.

We report comprehensive transport, electron microscopy and Raman spectroscopy studies on transition-metal chalcogenides Cu 1.89 Te single crystals. The metallic Cu 1.89 Te displays successive...

2022年4月15日 · Using a salt-assisted chemical vapor deposition method, we successfully realize the rational synthesis of the high-quality crystal of layered Cu 2 Te nanosheets. The energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy characterizations confirm the chemical composition of our as-grown Cu 2 Te nanosheets.

2021年5月24日 · Here, we systematically investigate the electronic structure and its temperature evolution of the less studied single crystal Cu2-xTe by the combination of angle resolved photoemission spectroscopy (ARPES) and scanning tunneling microscope/spectroscopy (STM/STS) experiments.
