2009年3月5日 · Here we present a femtosecond electron diffraction study of the structural changes in crystalline bismuth as it undergoes laser-induced melting.

2006年1月1日 · This paper reviews recent experimental and theoretical work on some low-index surfaces of the group V semimetal bismuth. The main focus is on the geometric and electronic structure, including the effect of the spin–orbit interaction, and on the electron–phonon coupling.

2024年5月13日 · To determine the structure and crystallinity of the vdW-moulded bismuth, we performed transmission electron microscopy (TEM), electron backscatter diffraction (EBSD) and Raman spectroscopy...

2013年4月9日 · The lattice response of bismuth nanoparticles to femtosecond laser excitation is probed by ultrafast electron diffraction. The transient decay time after laser excitation is observed to be longer for diffraction from the (012) lattice planes compared to that from (110).

2023年6月1日 · The simulated electron diffraction patterns of the pure β-bismuth and the half-layer bismuth section along [111] are shown in Figure 2e in orange and red, respectively. The 30° rotation between the two domains, as observed in the experimental diffraction pattern (see Figure 1 e), and also in the simulation of the hybrid stack, depicted in ...

2005年2月10日 · The epitaxial growth of Bi on Si(1 1 1) studied by spot profile analyzing low energy electron diffraction shows for low coverage rotationally disordered Bi cluster with preferred orientations following the threefold symmetry of the Si substrate.

2005年8月3日 · The surface structure of Bi (111) was investigated by low-energy electron diffraction (LEED) intensity analysis for temperatures between 140 and and by first-principles calculations. The diffraction pattern reveals a surface structure and LEED intensity versus energy simulations confirm that the crystal is terminated with a Bi bilayer.

2022年8月12日 · In this paper, we report the structural dynamics of polycrystalline bismuth (Bi) thin films in response to photoexcitation, visualized by mega-electron-volt ultrafast electron diffraction. The data reveal that the carrier–phonon scattering process involves phonon squeezing within sub-picoseconds (ps) and lattice thermalization within a few ps.

This paper reviews recent experimental and theoretical work on some low-index surfaces of the group V semimetal bismuth. The main focus is on the geometric and electronic structure, including the effect of the spin–orbit interaction, and on the electron–phonon coupling.

2023年11月13日 · These previous works have utilized in-situ low-energy electron diffraction technique to observe a structure transition from textured pseudo-cubic Bi (110) grains into hexagonal Bi (111)...
