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...

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...

030039: Real-time Nanomanipulation using AFM

An efficient system for manipulation of nano-sized objects would be greatly aided by the ability of an operator to "feel" the objects he/she is manipulating. Description The invention proposes an atomic force microscope (AFM) based Augmented Reality System consisting of an AFM connected to a haptic device allowing the operator to feel the nano-objects...
