Abstract
An in situ study of the growing surface of a diamond thin film is of great interest to many researchers in view of the outstanding physical properties of diamond. Recently, infrared-visible sum-frequency generation (IVSFG) has been proven to be a versatile surface spectroscopic probe with excellent surface and molecular specificity.1,2 In this paper we show that in addition to the vibrational properties revealed by the magnitude of the resonant sum-frequency susceptibility, IVSFG also contains interesting information about the surface electronic states.
