The proposal will lead to significant advances in the general area of QD research. Improving the understanding of current QD materials and devices is crucial towards enabling this technology to reach its full potential. This understanding will emerge from the extensive experimental program foreseen, which includes detailed gain and refractive index measurements as a function of temperature from 77K to above room temperature, femto-second pump probe spectroscopy to determine the fundamental timescales of the se novel structures and careful analysis of the efficiency and transport properties of these devices to reveal their fundamental transport and loss processes.
This information will greatly aid the development of new quantum dot material structures such as those based on Antimonide substrates and dot-in-a-dot structures. These materials will be the first of their kind in the world and the researchers role will be key in providing feedback to both fabricators and designers. Through this interaction, great progress will be made in the practical realisation of the great benefits of quantum dot materials and their extension to new wavelength ranges.
