Phononvälitteistä
Phononvälitteistä refers to a mechanism of interaction or energy transfer mediated by phonons. Phonons are quantized units of vibrational energy in a crystal lattice, akin to particles of sound or heat. In solid materials, atoms are not stationary but vibrate around their equilibrium positions. These vibrations are not independent; they are coupled, meaning the motion of one atom influences its neighbors. This collective motion can be described as waves propagating through the lattice.
Phonons represent the discrete energy levels of these lattice vibrations. When a phonon is created, it carries
This mediation is also fundamental to heat conduction in solids. Heat energy, in essence, is the collective
