Semiconductor nanocrystals have received an extraordinary degree of attention during thepast few years. The electronic, optical, photochemical, and thermodynamic properties of these materials are strongly size dependent, providing a rich area of research, with many potential applications1. It remains true that the range of phenomena that can be studied in nanocrystals is limited by the quality of available samples. In this paper we describe two advances in the preparation of nanocrystalline semiconductor samples. First is the preparation of CdS nanocrystals covalently bound to a metal surface; in this configuration it is possible to study the nanocrystals by photoemission. Second, we report the organometallic synthesis of GaAs nanocrystals.
