Phonon detection by double quantum dots

During the last few decades research has improved our knowledge and control over electrons and photons, enabling impressing advances for electronic and optoelectronic applications. The same degree of control is still lacking for phonons. The ability to manipulate phonons and phonon transport on a quantum level would lead to full control over heat flow in nanodevices. Beside improving thermoelectric devices, doing a part to solve the global energy crisis, and solving the thermal management bottlenecks affecting computer chips and data storage technologies, it could also lead to phonon transistors and the realization of phonon logic gates.

Deposition and Characterization of Wide Band Gap P-Type Metal Oxides for Photovoltaic Applications

Daily, the population in the world is increasing, along with the quantity of needed energy. However, the fossils are running out and climate change is a global concern now, thus, the demand for alternative energies is growing. Solar energy comes free by the sun light and, if well harvested, it could be a valuable and readily available alternative source of energy for humanity. In this work, we perform deposition and characterization of thin films of copper oxides to be used in photovoltaic devices.
