Chapter 5 - Semiconductor clusters and their use as precursors to nanomaterials

Abstract

On the synthetic continuum between small molecule precursors and larger semiconductor nanostructures, exist intermediate-sized clusters. The identification, characterization, and conversion of clusters have emerged as central topics in the field of nanoscience because of their importance as precursors and intermediates to technologically and commercially valuable materials. In this chapter, we examine the (i) synthesis, (ii) surface chemistry, and (iii) post-synthetic modification of semiconductor clusters, and then explore their (iv) use as precursors and intermediates in the synthesis of larger semiconductor nanomaterials. Finally, we provide an outlook to the future of semiconductor nanostructure synthesis and applications with a particular focus on the role of clusters in directing nucleation mechanisms and improving material function.
