Acquisition of high-quality three-dimensional electron diffuse scattering data [PDF]

arXiv, 2023
The diffraction patterns of crystalline materials with local order contain sharp Bragg reflections as well as highly structured diffuse scattering. The instrumental requirements, experimental parameters and data processing techniques for obtaining high-quality diffuse scattering data have previously been determined for X-ray and neutron diffraction ...

In-situ Investigation of the Early Stage of TiO2 epitaxy on (001) SrTiO3 [PDF]

, 2011
We report on a systematic study of the growth of epitaxial TiO2 films deposited by pulsed laser deposition on Ti-terminated (001) SrTiO3 single crystals. By using in-situ reflection high energy electron diffraction, low energy electron diffraction, x-ray

Automated crystal orientation mapping by precession electron diffraction assisted four-dimensional scanning transmission electron microscopy (4D-STEM) using a scintillator based CMOS detector [PDF]

, 2021
The recent development of electron sensitive and pixelated detectors has attracted the use of four-dimensional scanning transmission electron microscopy (4D-STEM). Here, we present a precession electron diffraction assisted 4D-STEM technique for automated orientation mapping using diffraction spot patterns directly captured by an in-column scintillator

Reflection high-energy electron diffraction oscillations on rotating substrates [PDF]

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1999
We compare different methods to measure reflection high-energy electron diffraction oscillations on rotating substrates. The best signal-to-noise ratio as well as the highest accuracy is obtained by measuring the full width at half maximum of the specular spot perpendicular to the surface.

Strain in epitaxial Bi2Se3 grown on GaN and graphene substrates: A reflection high-energy electron diffraction study

, 2015
Topological insulator (TI) has been one of the focus research themes in condensed matter physics in recent years. Due to the relatively large energy bandgap, Bi2Se3 has been identified as one of the most promising three-dimensional TIs with application ...

Feynman photon path integral calculations of optical reflection, diffraction, and scattering from conduction electrons [PDF]

Nuclear Instruments and Methods A1056 (2023) 168679, 2023
This paper describes the use of Feynman photon path integrals to compute the probability of detecting reflected, diffracted, and scattered photons at different points in space after interacting with conduction electrons. Five examples are given: (1) a thin parabolic sheet of conduction electrons (e.g.
