... the effect of the direct electron–phonon coupling across the interface and thus facilitate its study. Transient thermo-reflectance measurements using femtosecond laser pulses are performed on Au–Si samples while the simulation results based on a two-temperature model are compared with the measured data...

...Lan Jiang; Hai-Lung Tsai The two-temperature model has been widely used to predict the electron and phonon temperature distributions in ultrashort laser processing of metals. However, estimations of some important thermal and optical properties in the existing two-temperature model are limited...
