Advanced functionality with 3D controlled nanostructures

The project on Advanced Functionality with Three-Dimensionally Controlled Nanostructures (AFTDCN) is supported by the Deutsche Forschungsgemeinschaft (DFG) and the Japan Science and Technology Agency (JST). Its scientific research program is part of the international Strategic Japanese-German Cooperative Program on “Nanoelectronics”.

At the Paul Drude Institute (PDI), we investigate free-standing and hybrid semiconductor heterostructures, which are the basis for a new class of micro- and nano-electromechanical systems, in the framework of current-induced spin polarization, macroscopic quantum tunneling, and quantized phonon transport. These systems are important for ballistic transport on curved surfaces and for microtube ring resonators in optics. Innovative techniques are developed at the PDI to maintain the extraordinary properties of two-dimensional electron systems also on such nanostructures. This enables us to investigate entirely new physical phenomena of electron transport in a wide range of materials combinations and sophisticated structures. The work is performed at the PDI in close cooperation with two leading research institutions in japan, NTT Basic Research Laboratory in Atsugi and Tohoku University in Sendai, with a very long-standing experience in semiconductor physics.
