2. Measuring quantum systems with a tunnel junction
Abstract : This thesis is concerned with employing the statistics of charge transfer in a conductor as a tool for quantum measurement. The physical systems studied are electronic devices made by nanoscale manufacturing techniques. In this context quantum measurement appears not as a postulate, but as physical process. READ MORE

3. Single Junction and Tandem Junction Nanowire Solar Cells
Abstract : Solar cells based on silicon are successfully harvesting solar energy in established and increasingly widespread solar panels. However, their efficiency is limited by the Shockley–Queisser limit. For certain applications where high efficiency is the key figure of merit, the use of multi-junction solar cells is desirable.

4. The Functional Microstructure of Al/AlOx/Al Tunnel Junctions
Abstract : Josephson junction as a novel superconducting electronic component plays an important role in most small-scale superconducting systems. Particularly the Al/AlOx/Al tunnel junction, a high-performance junction made with a well-established microfabrication technology, is widely used as a building block of many quantum circuits.

5. Growth and Characterization of Tandem-Junction Photovoltaic Nanowires
Abstract : In order to satisfy the growing energy needs of our planet’s population, and at the same time mitigate global warming, sustainable energy sources such as solar energy are indispensable. In addition to conventional silicon-based solar cells, nanotechnology offers interesting approaches for complementary applications. READ MORE
