Surface scattering resonance absorption of free electron in nano structured materials

A physical model has been established for calculating the electronic transportation in nano structured material when it is irradiated by a laser pulse with a power density in a magnitude of GW/cm2. The Monte Carlo technique has been selected to deal with the electron scattering process. In the process of electrons absorbing laser energy, a surface scattering resonance absorption mechanism and a small-size effect can be found. The regularities of electron energy changes with laser wavelength, structure dimension, and orientation of nano-line have been analyzed.
