2021年11月19日 · We probe the electronic structure of monolayer 1T-NbSe 2 using scanning tunneling microscopy/spectroscopy (STM/STS). By combining our spectroscopic data with Hubbard-corrected density functional theory (DFT) calculations, we show that the gap is …
Charge-density wave mediated quasi-one-dimensional Kondo
2024年2月3日 · The stripe phase in monolayer NbSe 2 is caused by Se-deficient line defects generated during molecular beam epitaxy (MBE) growth, which leads to a charge density wave (CDW) phase transition ...
Single-layer CrI3 grown by molecular beam epitaxy
2020年7月15日 · Scanning tunneling microscopy (STM) was well adopted in in-situ investigating local structural and magnetic properties of MBE-prepared 2D magnetic materials at the atomic level [23], [24]. Here, we prepared single-layer CrI 3 on Au (1 1 1) and graphite substrates, respectively, using MBE in ultrahigh vacuum.
STM and MBE: one of the best combinations - IOPscience
2011年11月4日 · As a state-of-the-art growth method, molecular beam epitaxy (MBE) is a gifted technique for epitaxial growth with atomic-level control. In this paper, by giving several examples, we will show that an STM–MBE combined system is more powerful and unique for studies on low-dimensional and new functional materials.
