Abstract
For most undergraduate students, introductory quantum chemistry is a challenging subject with many uncommon, if not bizarre, ideas. It is important to relate quantum concepts to the "real" world. Semiconductor quantum dots can be used to introduce and reinforce important points of quantum mechanics and provide real-world applications that exploit quantum phenomena. Most stunning is the colorful demonstration of quantum confinement; few other instances allow direct observation of a quantum effect. Semiconductor nanocrystals can be qualitatively modeled as a particle in a box. This paper presents methods of fabricating nanocrystals, focusing on the pyrolysis of organometallic precursors. The relationship between energy and nanocrystal size is detailed, and the paper closes with an overview of applications of semiconductor nanocrystals.
