optical phonon मीनिंग इन हिंदी

उदाहरण वाक्य

1. However, exciting and harvesting the optical phonon poses a challenge.
2. Thus, the electron population is heated up to the optical phonon temperature and further generation is inhibited.
3. The down-conversion is simultaneously inhibited as the acoustic phonon population is heated to the optical phonon temperature.
4. There are a number of ways to excite a population of vibrations, i . e ., create a hot optical phonon population.
5. The drop in drift velocity at high electric fields due to intervalley scattering is small in comparison to high saturation velocity that results from low optical phonon scattering.
6. Electrons accelerated by an electric field are relaxed through the energy conversion to phonon ( in semiconductors, mostly optical phonon ), which is called Joule heating.
7. The polaron, a fermionic quasiparticle, should not be confused with the polariton, a bosonic quasiparticle analogous to a hybridized state between a photon and an optical phonon.
8. Regardless of method, the conversion efficiency is limited by the optical phonon temperature achieved as compared to the electron temperature within the device due to Carnot's theorem.
9. This efficiency ( \ eta _ { QE } ) is quantified by the tendency of a hot optical phonon to downconvert rather than generate an electron-hole pair, that is
10. The temperature of the optical phonon population is calculated by comparing the number of optical phonon to the number expected at a given temperature, which comes from the Bose-Einstein statistics.
