Notes Concentration of holes in the valance band of p type semi conductor In a p-type semiconductor, the concentration of holes in the valence band is higher than the concentration of free electrons in the conduction band. This is because the p-type semiconductor ...
Notes Concentration of electrons in the conduction band in n type semi conductor In an n-type semiconductor, the concentration of holes in the valence band is low, while the concentration of free electrons in the conduction band is high. This is because the ...
Notes Electronic heat capacity at low temperature Increase in thermal energy of system of N free electrons when their temperature is increased from 0 K to T K is△ U = U(T) - U(0)where f(...
Notes Two stream instability The electron plasma frequency, also known as the plasma frequency, is a characteristic frequency that describes the collective motion of electrons in a plasma.In a plasma, the positively charged ...
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 Ion acoustic wave Ion acoustic waves are a type of electrostatic wave that propagates through a plasma consisting of ions and electrons. They are generated due to the temperature and density fluctuations in ...
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 ...
