Phonon resonances in the optical nonlinearity induced by the mixing of pump and probe pulses are investigated in an a-sexithienyl vacuum evaporated thin film. We have performed femtosecond differential transmission spectroscopy at room temperature and at 20 K using excitation energies from 2.14 to 2
## Abstract The thermodynamic criterion of the mechanism of growth of thin films is reconsidered. It is shown that the supersaturation plays a significant role in determining the growth mode in addition to already discussed interrelation between the specific surface energies of the substrate, depos
