2005年6月10日 · The interaction between the (1 0 0) surface of SnTe single crystal and molecular oxygen was studied by means of X-ray photoelectron spectroscopy (XPS). Analysis of the obtained spectra shows that the mechanism of surface oxidation does not change in the range of oxygen exposure 10 8 –10 13 L.

2018年9月15日 · In this work we combine experimental techniques: angle-resolved X-ray photoelectron spectroscopy (ARXPS), Time Of Flight Secondary Ion Mass Spectroscopy (TOF-SIMS) and Raman spectroscopy to determine depth-resolved chemical composition profile of the surface of SnTe crystal subject to air exposure at room temperature over the …

2024年8月15日 · Here, we demonstrate how a topological crystalline insulator, SnTe thin films, can be prepared on highly oriented pyrolytic graphite and gold-plated mirrors through molecular beam epitaxy.

2023年9月5日 · X-ray photoelectron spectroscopy (XPS: SPECS, Germany) using a monochromatic Al K α X-ray source (h ν = 1486.61 eV, X-ray energy: 13KV, 100 W) was used to investigate the binding energy and chemical bonding

2023年5月4日 · Here, we report a thiol-free tin telluride (SnTe) precursor that can be thermally decomposed to produce SnTe crystals with sizes ranging from tens to several hundreds of nanometers.

In this work, we prepared SnTe (111), SnTe (001) and SnTe (211) TCI thin films by molecular beam epitaxy (MBE) for studying the role of TSSs and mirror symmetry in electrocatalytic HER performance.

2016年12月22日 · We report the determination of band alignment of PbTe/SnTe (111) heterojunction interfaces using X-ray photoelectron spectroscopy (XPS). Multiple core levels of Pb and Sn were utilized to determine the valence band offset (VBO) of the heterojunction.
