Notes Electron cyclotron resonance Electron Cyclotron Resonance (ECR) is a phenomenon in which electrons in a magnetic field absorb energy from an electromagnetic wave with a frequency equal to or near their cyclotron frequency. ...
Notes Electron plasma waves An electron plasma wave is a type of wave that propagates through a plasma, which is a gas made up of charged particles (ions and electrons). Specifically, an electron plasma ...
Notes Crystal Defect The imperfection in the solid due to the deviation from the periodicity of the crystal is called crystal defect.1. Point defect/ Lattice vacancy: The defect in the crystal that ...
Notes Theory of Plasma oscillation If the electron in a plasma are displaced from a uniform background of ions, electric field will be built up in such a direction as to restore the neutrality of ...
Notes Bloch theorem Bloch theorem is a fundamental result in the theory of solids that describes the behaviour of electrons in a periodic potential, such as the crystal lattice of a solid. The ...
Notes Doppler effect in light When there is relative motion between source and observer, there is apparent change in frequency of wave which is called Doppler's effect. In the case of light waves, the Doppler ...
Notes Jeans instability In the interstellar model, molecular clouds are the sites of star formation. Clouds must be in hydrostatic equilibrium for stability, which requires that internal pressure be in equilibrium with …
Notes Flux quantization in a superconducting ring Flux quantization is a fundamental property of superconducting rings, which is a consequence of the Meissner effect. When a superconducting ring is placed in a magnetic field, the magnetic field ...
