A1: Morphosynthesis of ceramic semiconductor and ferroelectric nanocrystals

Principle Investigators:

Prof. Dr. S. Polarz and Prof. Dr. V. Wittmann

About project A1:

For particle-based materials composed of defined nanocrystals, the ability to adjust the properties of the building blocks is vital. Such tuning can be achieved, when the shape gets correlated to the intrinsic anisotropy of the crystallographic system. For this purpose special additives with surfactant design will be synthesized and tailored for the interaction with inorganic surfaces. They will be used during the morphosynthesis of oxidic and non-oxidic semiconductor materials with ferroelectric characteristics. Furthermore, we aim at customizing the electronic properties of the particles via doping while preserving shape control.
