Fabrication Techniques for Quantum Dots

The nanotechnological expansion involves the innovation and designing of materials at the nanoscale regime with controlled properties. Production of nanomaterials with good crystallinity, shape control, and narrow distribution of size plays a significant role in QD-based devices and applications. Various strategies ranging from simple wet chemical methods to advanced atomic layer deposition strategies have been employed for the production of QDs. In this chapter, a prominent and detailed discussion of conventional techniques in addition to the up-to-date development in the synthesis of recent QDs is given. Synthesis routes based on the microwave or ultrasonically assisted and cluster-seed process are of great significance.
