label free and high resolution protein dna nanoarray analysis using kelvin Probe force microscopy
Nature Nanotechnology, 2007Co-Authors: Asher K. Sinensky, Angela M. BelcherAbstract:Using the Scanning Probe Technique known as Kelvin Probe force microscopy it is possible to successfully devise a sensor for charged biomolecules. The Kelvin Probe force microscope is a tool for measuring local variations in surface potential across a substrate of interest. Because many biological molecules have a native state that includes the presence of charge centres (such as the negatively charged backbone of DNA), the formation of highly specific complexes between biomolecules will often be accompanied by local changes in charge density. By spatially resolving this variation in surface potential it is possible to measure the presence of a specific bound target biomolecule on a surface without the aid of special chemistries or any form of labelling. The Kelvin Probe force microscope presented here is based on an atomic force microscopy nanoProbe offering high resolution ( 1,100 microm s(-1)), and the ability to resolve as few as three nucleotide mismatches.

Direct probing of Schottky barriers in Si nanowire Schottky barrier field effect transistors.
Physical review letters, 2011Co-Authors: Dominik Martin, Andre Heinzig, Matthias Grube, Lutz Geelhaar, Thomas Mikolajick, Henning Riechert, Walter M. WeberAbstract:This work elucidates the role of the Schottky junction in the electronic transport of nanometer-scale transistors. In the example of Schottky barrier silicon nanowire field effect transistors, an electrical Scanning Probe Technique is applied to examine the charge transport effects of a nanometer-scale local top gate during operation. The results prove experimentally that Schottky barriers control the charge carrier transport in these devices. In addition, a proof of concept for a reprogrammable nonvolatile memory device based on band bending at the Schottky barriers will be shown.

Probing dopants at the atomic level
Nature Physics, 2008Co-Authors: Michelle Y. SimmonsAbstract:A more comprehensive understanding of coupled quantum systems could soon be in reach with a capacitance-based Scanning Probe Technique that explores the behaviour and interaction of individual dopant atoms in a semiconductor.
