Ultrafast Dynamics at Semiconductor and Metal Surfaces

J. BOKOR 1

1 Head of the Laser Science Research Department at AT&T Bell Laboratories, Holmdel, NJ 07733.

A variety of important dynamical phenomena at metal and semiconductor surfaces are now being investigated with the use of new ultrafast measurement techniques involving lasers and nonlinear optics. Understanding of the rates and mechanisms for relaxation of optical excitations of the surface itself as well as those of adsorbates on the surface is providing new insight into surface chemistry, surface phase transitions, and surface recombination of charge carriers in semiconductors.
