- However, exciting and harvesting the optical phonon poses a challenge.
- Thus, the electron population is heated up to the optical phonon temperature and further generation is inhibited.
- The down-conversion is simultaneously inhibited as the acoustic phonon population is heated to the optical phonon temperature.
- There are a number of ways to excite a population of vibrations, i . e ., create a hot optical phonon population.
- 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.
- Electrons accelerated by an electric field are relaxed through the energy conversion to phonon ( in semiconductors, mostly optical phonon ), which is called Joule heating.
- 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.
- 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.
- 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
- 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.
- 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.
- A higher optical phonon energy results in fewer optical phonons at a particular temperature, and there are therefore fewer scattering centers, and electrons in wide bandgap semiconductors can achieve high peak velocities.
- In addition this typical inefficiency, hot optical phonon populations tend to downconvert into multiple low-energy, acoustic phonon modes ( whereas photons typically do not downconvert into low energy infrared waves ).
- Local and spatial thermal non-equilibrium for the optical phonon and electron populations ( T _ { p, \ mathrm { O } } and T _ e ) for variations in the length.
- If the band gap and optical phonon mode are resonant, and the optical phonon tends to generate electrons, the phonovoltaic cell can approach the Carnot limit as T _ { pv } \ rightarrow 0.
- If the band gap and optical phonon mode are resonant, and the optical phonon tends to generate electrons, the phonovoltaic cell can approach the Carnot limit as T _ { pv } \ rightarrow 0.
- While the thermoelectric generator converts heat, a broad spectrum of phonon and electron energy, to electricity, the pV cell converts only a narrow band of phonon energy, i . e ., only the most energetic optical phonon modes.
- Where T _ \ mathrm { pV } is the temperature of the pV cell and T _ { p, \ mathrm { O } } is the temperature of the optical phonon population, as dictated by the Bose-Einstein statistics.
- Furthermore, the pV cell requires a material wherein a hot optical phonon prefers to produce an electron rather than multiple low energy acoustic phonons ( \ dot { \ gamma } _ { e-p } ^ * \ rightarrow 1 ).
- The resulting mobility is expected to be proportional to " T " " 3 / 2, while the mobility due to optical phonon scattering only is expected to be proportional to " T " " 1 / 2.
