Inaugural Lecture


Prof. Jennifer Rupp: Nano-Elektronik und -Ionik: Memristive Speicher und Energie Konversion (video, 08.02.2013)

We research mass and charge transport for information storage and energy devices. Our philosophy is to either reduce energy consumptions at increased functionality and density of memory circuits or to produce energy based on direct hydrocarbon usage. This involves basic research in mass and charge transport at single metal-oxide interfaces and electrochemistry of micro-chip devices with functional materials.

Prominent examples for information research are new Resistive Random Access Memory (ReRAM) switches as next generation memories in portable electronics, neuromorphic circuits to mimic human brain functions, or, to realize functional see-through iono-electronic circuits for potential aviation, automotive or computing applications.

The second area of research focuses on energy producing devices such as fuel cells. These are either used to generate power or as electrolysers to allow for electrical to chemical energy conversion. Among these micro-solid oxide fuel cells are focused being miniaturized fuel cells based on Si-chips to convert chemical into electrical energy for replacements of today`s Li-ion batteries. Main gain is the independence on the electricity net and direct operation on hydro-carbons. Besides, a second type of liquid-solid cell is considered to convert access solar energy in form of fuels and vice versa for satellite applications during night times. Here, new thin film model electrode materials are developed and tested with partners.

All of these applications are based on the transport of electric charge via an metal/oxide/metal thin-film structure (the metal serving as electrode). Even though there are interesting potential applications electric transport needs to be understood in detail, including such important aspects as space-charge formation or the interaction between strain and charge- and mass transport at the interfaces i.e. electrode-oxide interface. This involves also suggestions of new materials or the design of new microstructures to allow for better understanding in model experiments and optimization of device performances.

We work on these basic questions as well as on very applied aspects such as on new micro-chip designs for these electrochemical devices, their processing, testing and performance optimization.
