The inset shows normalized XAS spectra for different coverages of Fe on Bi2Se3 (background contributed by pristine Bi2Se3 is removed).

1984年8月1日 · In this paper we compare the XPS and UPS (ultraviolet photoelectron spectroscopy) spectra of amorphous Bi2Se3 with those of crystalline Bi2Se3 and discuss the local structure of amorphous Bi-doped chalcogenides.

2020年7月27日 · Here we report on a promising route to fabricate micron-scale continuous carpets of monolayer thick FeSe on Bi 2 Se 3 topological insulators. In contrast to previous procedures based on ultraflat bulk Bi 2 Se 3 surfaces, we use molecular beam epitaxy grown Bi 2 Se 3 films with high step-edge densities (terrace widths 10–100 nm).

Bi2Se3 is MAX Phase-derived structured and crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three Bi2Se3 sheets oriented in the (0, 0, 1) direction. Bi3+ is bonded to six Se2- atoms to form a mixture of corner and edge-sharing BiSe6 octahedra.

2023年2月1日 · Bi 2 Se 3 thin films with the different substrate were grown using thermal evaporation technique. Basic charecterization like EDAX, XRD and SEM were done for structural and morphological study. Resonance corresponds to A 1 g 1, E 2 g, and A 2 g 2 were confirmed by RAMAN spectroscopy.

Bi2Se3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of two Bi2Se3 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Bi3+ sites.

XAS and respective XMCD spectra of FeSe on Bi2Se3 taken at temperatures T = 200, 100, and 6 K. The inset shows the polar measuring geometry (Θ = 0°) and the field orientation. XMCD signals were...
