THERMALIZATION TIME
- Can we define
- Momentum and energy relaxation mediated by electron-ripplon scattering
-
-
-
- collision time: tc ~ 20-50 ns (plasmon linewidth) momentum relaxation time
- quasi elastic scattering: electrons scattered by ripplons with
wave vector :
energy:
- Many (~1000) collision needed to dissipate electron energy:
-
- Thermalization time within electron plane
R-radius of electron pool,
ct transverse sound velocity
- On time scales we can define
