Experimentelle Halbleiterphysik

Prof. Martin Stutzmann

Forschungsgebiet

Our work at the Walter Schottky Institut deals with various aspects of new and non conventional semiconductor materials and material combinations: semiconductors with a wide bandgap (GaN, InGaN, AlGaN, diamond, SiC) disordered semiconductors (amorphous, nanocrystalline, and polycrystalline) advanced thin film systems (silicon-based luminescent layers, thin film solar cells, organic/anorganic heterosystems, biofunctionalized semiconductors). Most of these material systems are prepared in our group by suitable deposition techniques (MBE, MOCVD, Plasma-enhanced CVD, e-beam evaporation, sputtering). Their efficient optimization is based on the large pool of structural, optical, and electrical characterization techniques available in our Institute. Complementary to the usual spectroscopic techniques we have developed and employ a variety of highly sensitive methods which enable us to study in particular the influence of defects on the electronic performance of materials and devices. Such techniques include subgap absorption spectroscopy, optically induced capacitance spectroscopy and, in particular, modern spin resonance techniques which are applied to various materials systems and devices for spintronics.

In addition to the preparation and characterization of new semiconductor materials we also work on the modification and processing of semiconductors with pulsed high power laser systems (laser-crystallization, holographic nano structuring, laser-induced etching) and investigate the potential of new material systems for novel device structures. Recent examples include nano structured thin film solar cells, high electron mobility transistors based on AlGaN/GaN hetero structures, as well as UV-detectors, sensors and biosensors.

Optoelectronic Characterization of Hybrid Systems of Organic and Inorganic Semiconductors
Hybrid systems of organic and inorganic semiconductors are attractive for novel types of solar cells and light emitting devices, as they combine the high carrier mobility and stability of inorganic materials with the low production costs and the flexibility of organic semiconductors. In order to identify the most promising material combinations, the properties of the hybrid systems need to be understood in detail. In this work, the organic semiconducting molecule F16CuPc (Fig. 1) will be deposited on inorganic semiconductors like Si, SiC, or GaN by organic molecular beam deposition. After optimizing the organic thin film growth, the resulting hybrid systems (Fig. 2) will be characterized with respect to their structural and optoelectronic properties. The aim of this project is to gain information about the influence of the choice of organic and inorganic semiconductor materials on the organic/inorganic interface of the heterojunction. For further information, please contact Hannah Schamoni (Hannah.Schamoni(at)wsi.tum.de). To apply, please submit your CV and your transcript of records.
