Direct detection of electron backscatter diffraction patterns.
We report the first use of direct detection for recording electron backscatter diffraction patterns. We demonstrate the following advantages of direct detection: the resolution in the patterns is such that higher order features are visible; patterns can be recorded at beam energies below those at which conventional detectors usefully operate; high precision in cross-correlation based pattern sh...
متن کاملMagnetic Domain Structure and Crystal Orientation Revealed by a Forescatter Detector and Electron Backscatter Diffraction
Imaging magnetic domains for soft magnetic materials using scanning electron microscopy (SEM) typically requires a specially modified setup. These modifications can include higher beam acceleration voltages, modifications of the sample and detector geometry, and/or specialized detectors to detect the spin polarization of secondary electrons [1,2]. In this research, a method is presented for ima...
متن کاملCrystallographic preferred orientations analysis of quartz crystals in Psammite using electron backscatter diffraction,western Ireland
The present study investigates the crystal preferred orientation (CPO) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (EBSD) on quartz crystals from north of the Renvyle-Bofin Slide (RBS) nearLetterfrack in western Ireland. Complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...
متن کاملMany-beam dynamical simulation of electron backscatter diffraction patterns.
We present an approach for the simulation of complete electron backscatter diffraction (EBSD) patterns where the relative intensity distributions in the patterns are accurately reproduced. The Bloch wave theory is applied to describe the electron diffraction process. For the simulation of experimental patterns with a large field of view, a large number of reflecting planes has to be taken into ...
متن کاملAnalysis of Kikuchi band contrast reversal in electron backscatter diffraction patterns of silicon.
We analyze the contrast reversal of Kikuchi bands that can be seen in electron backscatter diffraction (EBSD) patterns under specific experimental conditions. The observed effect can be reproduced using dynamical electron diffraction calculations. Two crucial contributions are identified to be at work: First, the incident beam creates a depth distribution of incoherently backscattered electrons...
