Electron temperature is a measure of the average kinetic energy of electrons within a system, typically in the context of plasma physics or semiconductor physics. It represents the temperature at which electrons would have the same average energy as the particles in thermal equilibrium. Electron temperature is an important parameter in various research areas such as plasma physics, where it influences the behavior and properties of plasma, such as its stability and energy transfer mechanisms. It is also crucial in semiconductor physics, where it affects the conductivity and performance of electronic devices. Researchers often study electron temperature by measuring the energy distribution of electrons using techniques such as Langmuir probes, Thomson scattering, or electron energy analyzers. Understanding and controlling electron temperature is essential for optimizing the performance of various plasma-based technologies, such as plasma processing, fusion reactors, and semiconductor devices.
