Nanotechnology devices based on quantum dots have very interesting applications because of the unique characteristics that quantum dots exhibit. In addition to the very small size and operation almost at the speed of light, many important characteristics of quantum dots such as absorption and extinction can be exploited to design devices with a wide range of applications. The study of metallic quantum dots is also a very exciting and interesting field in engineering because of their immense application and relevance to Surface Enhanced Raman Spectroscopy (SERS); In this thesis, the variation in absorption spectra over a changing array of parameters has been studied. The objective is to look for tunability for various materials and sizes of quantum dots. Extinction spectra and electric field intensities over a range of substrates and for various sizes of spherical gold (Au) and silver (Ag) nanoparticles have been simulated. Important parameters such as suitable size of metal nanoparticle, surrounding semiconductor substrate, and wavelength of incident light for achieving highest electric field intensity have been proposed on the basis of simulations.
