Nanoparticles for Novel Electronic Devices

Currently, most electronic devices are manufactured starting from silicon wafers, an approach which is inherently highly limiting with respect to materials and substrates. The remote synthesis of cyrstalline semiconductor nanocrystals, their deposition on any kind of substrate and the formation of device structures around them is a new paradigm, which may enable printable electronics on flexible substrates and novel devices based on combinations of particles from different materials. Our group is involved in the development of approaches for the fabrication of high-quality crystalline semiconductor nanoparticles with well defined shapes. In collaboration with researchers in Electrical Engineering, we pursue the manufacture of novel nanoparticle-based devices.
