Electronic transport in low-dimensional GaAs/AlGaAs systems

In my Ph.D. work I have developed a novel field effect transistor (FET), which is fabricated by Cleaved- Edge- Overgrowth (CEO) using molecular beam epitaxy. This CEO FET allowed me to study two-dimensional electrons that travel in, or close by, a semiconductor superlattice. Based on this design I also fabricated and studied ultra short channel vertical transistors with less than 50 nm gate lengths.

Silicon On Insulator (SOI) technology and devices

In collaboration with my Diploma student M. Huber I have developed a new method for ultra-high resolution thermal oxidation on Silicon- On- Insulator materials (focused laser beam induced oxidation). Using this method we have successfully fabricated in- plane- gate transistors with channel widths in the 100 nm range

Neuromorphic Analog VLSI Motion Sensor Arrays

At Caltech in the group of Prof. Koch I have developed several new algorithms for visual motion detection. I have implemented these algorithms using standard CMOS processes as real- time sensors in pixel- parallel architecture, using analog VLSI technology
