The Paul Drude Institute for Solid State Electronics (PDI) is a research facility that is sponsored by the Forschungsverbund Berlin and a member of the Gottfried Wilhelm Leibniz Scientific Association . The Institute is based at Hausvogteiplatz in Berlin-Mitte , its research activities are the basic research in the fields of physics and engineering sciences and the fields of materials science / materials science and electronics / optoelectronics associate.
history
The institute emerged from the "Central Institute for Electron Physics" of the former Academy of Sciences of the GDR . Based on a recommendation by the Science Council , the institute was re-established on January 1, 1992 and headed by Klaus Ploog until 2006 . Henning Riechert was then director of the institute until the end of 2019.
The institute is named after the German physicist Paul Drude (1863–1906), who conducted research in the fields of optics and electronics and gave his name to the Drude theory .
tasks
The PDI conducts basic research on nanostructured semiconductors and is involved in the development and implementation of novel concepts for future components in information and communication technology .
Research focuses on the one hand III-V semiconductors based on aluminum , gallium and indium as well as nitrogen and arsenic , and on the other hand hybrid ferromagnet semiconductor structures. In recent years other materials have been added, including semiconducting oxides, e.g. B. Ga 2 O 3 , as well as 2D materials , e.g. B. graphene and hexagonal boron nitride . Among other things, the crystal growth processes are investigated using molecular beam epitaxy . Furthermore, fundamental optical, electrical and structural properties of the semiconductor layers and structures produced in this way are the subject of research. Where possible, ways to possible applications are also shown.
This involves the generation, amplification, transmission and manipulation of light as well as the development of new concepts for the coding, transmission and processing of information based on the quantum states of individual photons or electrons ( spintronics ). Current topics also include the growth and characterization of nanowires , surface acoustic waves to control elementary excitations (photonons, electrons, spins), phase change materials and quantum cascade lasers .
The research is divided into three departments: epitaxy (primarily molecular beam epitaxy , MBE), semiconductor spectroscopy and microstructure analysis. However, key issues are dealt with across departments.
Cooperations
The PDI cooperates closely with university and non-university institutions and is involved in many third-party funded projects.
In the university area, there is close cooperation with the Institute for Physics, Experimental Physics and Materials Science Department of the Faculty of Mathematics and Natural Sciences I at the Humboldt University in Berlin .
Infrastructure
The acting head of the institute is Lutz Geelhaar, head of the epitaxy department. The joint appointment procedure with the Humboldt University to fill the director's position is currently underway. About 100 people work at the institute.
The total budget of the institute was 10.9 million euros in 2019, of which around 9.5 million euros were funded half by the federal government and half by the federal states.
The Institute operates, among other things, about a dozen plants for molecular beam epitaxy , various optical measuring stations ( photoluminescence , cathodoluminescence , FTIR , UV Raman spectroscopy ...), several transmission electron microscopes , scanning electron microscopes and scanning probe microscopes , and an integrated growth and measurement set-up at the Berlin synchrotron (Elektronenbeschleuniger- and storage ring) BESSY . It has its own clean room .
