phonon emission मीनिंग इन हिंदी

Here, the + corresponds to phonon emission and for phonon absorption during the scattering event.
Namely, a concerted emission of phonons can lead to coherent sound and an example of concerted phonon emission is the emission coming from quantum wells.
Molecular excitons typically have characteristic lifetimes on the order of nanoseconds, after which the ground electronic state is restored and the molecule undergoes photon or phonon emission.
where the term \ hbar \ omega _ q accounts for phonon emission or absorption and the term \ Delta E _ C is non-null for inter-valley scattering.
The disorder-related mode ( D peak ) is a phonon mode at 1300 cm " 1 and involves the resonantly enhanced scattering of an electron via phonon emission by a defect that breaks the basic symmetry of the graphene plane.
