Materials for Micro- and Nanoelectronics

The activities of the department Materials Research are focused on this research program.

Materials research at IHP targets the integration of new materials into the technology to achieve additional, better or innovative functionalities. It also gears towards the preparation of new research fields at the institute.

Subject of the research are new high-k dielectrics and the research of new concepts for high-performance circuits using nanostructures or optical data transmission. The latter work is done at the Joint Lab IHP / BTU Cottbus.

Current focal points of the activities with high-k dielectrics are ternary alloys with praseodymium for future applications in MIM capacitors, memories and transistors as well as for epitaxy mediation for high quality epitaxial semiconductor layers (silicon-insulator-silicon stacks). Additionally, new materials for SAW filters and non-volatile memories are evaluated.

Silicon materials research is the subject matter of the Joint Lab IHP / BTU. Silicon properties are tailored to enable new applications and to improve existing ones.

Focuses are initial basic research for Si-based light emitters for optical data transmission, defect engineering for future silicon wafers, self organized adsorption of biomolecules on the silicon surface, band structure design and charge carrier transport in Sibased quantum structures, and the control of electrical properties of crystal defects in solar silicon.
