Semiconductor quantum dots

By (author)Mark Green

The fi eld of nanotechnology is growing. The tunability of nano-objects such as semiconductor quantum dots (SQDs) has spurred interest in chemical synthesis. In this regard, this book’s arrival is timely. It groups the various synthesis techniques for popular SQDs, comprised of 295 pages distributed among seven chapters and a comprehensive subject index. Preparation methods for II-VI, II-V, and IV-VI SQDs are described in the fi rst three chapters. The fi rst chapter introduces and develops various organometallic routes to the synthesis of Zn and Hg chalcogenides and anisotropic growth of Cd-based chalcogenides such as tetrapods and their alloys. Properties of Group III phosphides, nitrides, arsenides, and antimonides, which have different optical properties compared to II-VI semiconductors, are discussed in chapter 2. This chapter also reviews the tuning of SQD properties via dehalosilylation reactions and non-coordinating solvent routes.

It is shown that the quantum yield can be increased by varying precursors and their quantities. Anisotropic nanoparticles with rod-like morphologies have also been examined in terms of challenges faced during their synthesis. Lead-based chalcogenide properties and synthesis routes are outlined in chapter 3. Chapter 4 deals with the synthesis of other chalcogenides and pnictide-based materials. Ternary copper-based chalcogenide core-shell and II3-V2 quantum dots include CuInSe2 and Cd3P2, respectively, among many others. Chapter 5 discusses surface passivation by means of synthesizing an inorganic capping layer or a core- shell structure. This thorough chapter is of fundamental and practical interest. It describes Type I and Type II core shells and multiple shell structures targeting a higher quantum yield.
