050123: A Reliable Process for Fabricating Single Nanowires and Nanotubes

In a broad class of future nano-devices, a key challenge will be to construct connections between electrodes using single carbon nanotubes (CNTs) or semiconductor nanowires (NWs). Current methods have major difficulties with repeatability and the ability to eliminate uncertainties. A major problem is that growing NWs or CNTs across an electrode...

050122: Pneumatic Nano-Probe Tip for Nano-Manipulation and Manufacturing

A major problem with nano-manipulation is holding the target. Due to the lack of micro force/flow feedback, the target is often destroyed during its manipulation. It would be highly desirable to have a means for picking up and releasing nano-objects without the above difficulties. Description The current invention addresses current operational problems...

050034: Improved AFM Manipulation of Nano-Objects

In traditional atomic force microscope (AFM) based nano-manipulation systems, a cantilever is used as the probe tip to manipulate nano-sized objects. Because of the need for good contact with the object, a "pre-loaded" force must be exerted by the cantilever on the object, making it difficult for an operator to "feel" the object or to adjust and...
