Electrically-Driven Nanowire Devices for Sensors and Photonics — •Oliver Hayden — Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA, current address: IBM Research GmbH, Zurich Research Laboratory, CH-8803 Rueschlikon, Switzerland

Semiconducting nanowires are one of the most promising low dimensional materials for the bottom-up fabrication of nanodevices. The application of photonic and electrical devices from silicon and cadmium sulphide nanowires is presented. Ion-sensitive field effect transistors are formed with silicon nanowires and nanotubes, which allow label-free observation of immunological reactions with single virus sensitivity. Nanoscale light emitting diodes are integrated in microfluidic channels and used as intrinsically confocal light sources. These LEDs were applied to demonstrate single analyte detection and cellular imaging. The additional integration of nanowire avalanche photodiode detectors allows even optoelectronic coupling on the nanoscale.
