Abstract

This chapter discusses surface photoluminescence and surface second-harmonic generation. Bulk photoluminescence is strongly influenced by surface conditions: the role of de-excitation processes taking place at the surface is phenomenologically quantified by the surface recombination velocity. Surface states can contribute to pair recombination either with radiative or non-radiative processes. Second-harmonic generation (SHG) is observed in media lacking inversion symmetry. Detection of surface SHG is made possible by the breaking of inversion symmetry at the surface of centrosymmetric crystal. In principle, with very short laser pulses it is possible to obtain information also on dynamical processes.
