Dr. Stefan Ludwig, Department of Physics, Ludwig-Maximilians-University Munich (LMU)

We offer up to three exciting experimental PhD projects in the field of nanoelectronics including quantum information processing and spintronics, thermoelectrics and quantum transport in nanowires, and low‐dimensional systems at ultra‐low temperatures.

Project
The project involves quantum transport experiments on nanowires (at cryogenic temperatures) and is based on a local collaboration with Dr. Gregor Koblmüller and Prof. Gerhard Abstreiter, both TU-Munich, who provide nanowires and expertise in their handling and characterization. The first challenge will be to develop reliable lithography processes to contact the wires and to define coupled quantum dots. Once we have working structures we have many options including the study of complex quantum systems with several capacitively coupled quantum dots in separate wires, applications in spin based quantum information processing, fundamental properties of one-dimensional systems, and more. One particular interesting possibility is the study of the thermoelectric effect in nanowires (containing quantum dots) as such systems promise very efficient heat-to-electric power conversion on the one hand, but still raise fundamental questions on the other hand.

Requirements:Are you enthusiastic about a fundamental understanding of nanoscale electronic quantum circuits? Are you thrilled by solving the complex puzzles of interacting nanoscale solid state systems possibly at nonequilibrium? Are you interested in fabricating your own nanostructures in our cleanroom facilities? Would you like to perform challenging experiments at ultra‐low temperatures in a complex lab environment? If all these questions excite you and if you already have a solid background in basic quantum mechanics and solid state physics, you would enjoy working in our group and should apply for a personal interview.
