Abstract:
Low dimensional semiconductor crystals structures otherwise known as quantum dots are in possession of unique optoelectronic properties that allow the flow of electrons to be harvested instantaneously. The advent of quantum dot for various technological applications is motivated by their flexibility of their bandgap supporting their capability to tap power from the visible spectrum as well as the invisible infrared through absorbable wavelength ranges from about 700 nanometre to 10 micron. Besides the wide energy harvesting range, quantum dot utilizes small to area for high energy production.
