Ultrafast Electron Diffraction: How It Works | SLAC National ...
Ultrafast Electron Diffraction: How It Works This animation explains how researchers use high-energy electrons at SLAC to study faster-than-ever motions of atoms and molecules relevant to important material properties and chemical processes.
Davisson-Germer: Electron Diffraction - PhET Interactive …
Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability.
How to demonstrate electron diffraction in the classroom
This demonstration shows that an electron beam is diffracted when it passes through graphite, showing electron wave behaviour and diffraction patterns.Regist...
Electron Diffraction | Virtual Laboratory of Physics - UFC
In the Electron Diffraction simulation, a circle represents the front view of the glass globe of an electron diffraction tube. A 6.3 V source represents the source that feeds the tube filament that is heated and releases electrons through the thermionic effect, also called the Edson effect.
Physclips - Diffraction - UNSW Sites
Diffraction from monochromatic sources. Continuous spectra and line spectra, absorption and emission spectra. The hydrogen spectrum and the origins of quantum mechanics.
Electron diffraction - Wikipedia
This article provides an overview of electron diffraction and electron diffraction patterns, collective referred to by the generic name electron diffraction. This includes aspects of how in a general way electrons can act as waves, and diffract and interact with matter.
SAED | Software Suite for Electron Diffraction Simulation and …
Key tasks in electron diffraction analysis include determining the zone axis, indexing diffraction patterns for phase identification, and orienting crystal grains. To enhance structural interpretation and modeling, a projected atomic potential (difference) map can aid in interpreting high-resolution electron microscopy (HREM) images.
PhET Simulation: Davisson-Germer: Electron Diffraction - AAPT
2016年8月18日 · This webpage contains an interactive simulation that replicates the Davisson-Germer experiment of electron diffraction off of materials, a historically important verification of the wave-nature of quantum systems.
Davisson-Germer: Electron Diffraction - PhET
Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability. Recognize that electrons are reflected from a lattice mostly at certain angles due to wave interference. Overview of sim controls, model simplifications, and insights into student thinking ( PDF ).
NYLearns.org - Davisson-Germer: Electron Diffraction by PhET
This simulation will allow students to simulate the original experiment that proved that electrons can behave as waves. Students watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability.
