Abstract

Abstract

Semiconductor nanocrystal or quantum dots are Nano particles composed of ten to few hundreds of atoms but confined in a very small region. These are zero dimensional materials and are gaining attention to the researchers because of their interesting optical, electronic and opto-electronic properties compared to bulk. Quantum mechanical confinement plays a key role in determining the peculiar behaviour compared to bulk. Various preparation methods such as chemical, colloidal synthesis, electrochemical and lithographic technique are described. Characteristic properties of quantum dots are described by High resolution Transmission electron microscope (HRTEM), Scanning Transmission electron microscope (STEM), and Raman spectroscopy measurement etc. It has important applications in wide range of field such as biological, medical and opto-electronic devices.

 

Keywords: semiconductor, quantum dots, mechanical, photon energy, exciton Bohr diameter
