electron wave उदाहरण वाक्य

Different imaging methods therefore attempt to modify the electron waves exiting the sample in a way that provides information about the sample, or the beam itself.
The ansatz is the special case of electron waves in a periodic crystal lattice using Bloch waves as treated generally in the dynamical theory of diffraction.
The interaction of the electron wave with the crystallographic structure of the sample is complex, but a qualitative idea of the interaction can readily be obtained.
His 1924 thesis " Recherches sur la th�orie des quanta " ( Research on the Theory of the Quanta ) introduced his theory of electron waves.
"' Quantum confinement "'can be observed once the diameter of a material is of the same magnitude as the de Broglie wavelength of the electron wave function.

For a given nuclear isomer in two different physical or chemical environments ( different physical phases or different chemical combinations ) the electron wave functions are also different.
The electron wave ends up producing an interference pattern because the portion of the wave directed towards the 2D detector interferes with the portion directed away from the detector.
The electron wave can only pass through the constriction if it interferes constructively, which for a given width of constriction, only happens for a certain number of modes N.
The researchers suggested that electron waves could be imaged when interacting with a static electric field as long as the de Broglie Wavelength of these electrons was large enough.
When utilizing a Field emission source and a specimen of uniform thickness, the images are formed due to differences in phase of electron waves, which is caused by specimen interaction.
