The fast depletion of natural energy sources and the rising cost of fossil fuels have already been threatening our daily life since the turn of this century. If we are going to keep the same level of living standard in the future and for the future generations, energy saving and a more efficient energy usage are a must for all of us living today. The concepts of renewable energy and energy efficiency go hand in hand. These two concepts are considered to be the “twin pillars” of the policies regarding sustainable energy. To make the most of the sustainable energy policy there needs to be simultaneous application of strategies regarding renewable energy and efficient use of energy. The proposed program presented here targets at the development of a wide variety of nanoscale devices with potential applications in energy saving and high efficiency. The aim of this program is to propose, fabricate and characterize novel energy-efficient devices based on semiconductor nanostructures and quantum devices for achieving desired figures of merit. These include semiconductor plasmonic luminescent coolers, light emitting devices of enhanced luminescence efficiency with magnetic field, and embedded QDs for conversion efficiency enhancement in solar cells. However, most of the designs are still in the stage of theoretical investigation and there is a big challenge to integrate them in real applications. This is a collaborative program among theoreticians and experimentalists, physicists and technologists. The combined and diverse talents of this team will enable us to tackle the problem from different angles. This project is made up of four separate but strongly related parts: (1) semiconductor cooling chips (2) energy-efficient optoelectronic nanodevices (3) quantum dot embedded solar cells for better energy efficiency (4) model, characterization, and theoretical analysis of nanostructures for green electronics. We propose a comprehensive research plan which builds at the intersection of several important nano, material and optical technologies of this century. We plan to investigate areas in which these technologies overlap to provide new functionality. Some key technical goals and operational features of our plan are: • Development of semiconductor luminescent coolers incorporated with plasmonics for higher cooling power and lower temperature operations • Demonstrate effects of applied magnetic field on photocurrent generation in light emitting devices and solar cells • Development and adjustment of novel nanolithography and controlled self-assembled growth techniques of Si, InAs, InSb, and GaSb quantum dots embedded in photovoltaic cells of various kinds of host materials • Demonstration of photo-response and energy conversion in nanoscale photovoltaic cells • To develop a computational multiscale approach for the optimization of the highly efficient semiconductor nanodevices. • To identify and model nanoscale size effects and characteristics, which are crucial for the field control, optical properties, and thermal management of semiconductor nano-devices • A team of researchers who have substantial research experience in their respective fields and have a demonstrated commitment to collaborative research • Strong support and commitment from the Center of Nano Science and Technology at the National Chiao Tung University to support the research needs of this program The eventual success of this program is dependent upon our thorough understanding on material itself and at the same time a viable technology that combines the nanotechnology with state-of-the-art characterization techniques. The proposed program is designed to tackle the most critical issues of energy conservation and energy efficiency built from semiconductor nanostructures.
