Image - Created using AFM tip.

A height AFM (atomic force microscope) image of the Rowland institue motto, “Imaginative Experimental Science” scribed using an AFM tip on a plastic surface. The scan size is 20 by 20 micrometers. The same AFM tip is used for scribing and imaging.

Nanoelectronics and Nanosensor Group

The electrical conductance of many nanoscale materials is strongly affected by a local electrostatic and electrochemical environment. This unique property can be utilized to build a nanosensor whose spatial resolution is comparable to the size of the sensor itself. The objective of our research is to investigate the electron transport properties of various nanoscale materials, including carbon nanotubes, semiconducting nanowires and single molecules, and to develop nanoscale sensors based on them.
