Synthesis, Properties and Potential Applications of Semiconductor Quantum Particles

Abstract

Studies of quantum dots (Q dots) or nanometer sized compound semiconductors with diameters in the range of 1-20 nm have generated a great deal of interest due to fundamental and technological applications. A number of devices have already been fabricated employing quantum dots. This paper presents the recent advances in the synthesis of compound semiconductor quantum dots and their potential use in electronic devices. Our work on self-organization of Q-dots using a wet chemical route has also been presented. Optical properties of these Q-dots using absorption spectroscopy technique have been discussed in the light of the existing theoretical models.
