Notes 2 years ago Flag 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 2 years ago Flag 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 2 years ago Flag 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 2 years ago Flag 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 2 years ago Flag 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 2 years ago Flag 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 2 years ago Flag 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 2 years ago Flag 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 ...
