Dr. North takes you to the nanoscale with his own original works. In this series Dr. North has micro-machined and nano-fabricated structures too small for the eye to see. In fact, they are too small for a microscope to see. Not a whole lot to look at you’re thinking.
By using a scanning electron microscope Dr. North has bounced electrons off these structures, collected the ejected electrons, and then recreated an image of the structure. While scanning electron microscopy is a standard technique, the techniques used to create the structure are not. Dr. North developed these techniques in a hundred million dollar cleanroom, mixing a heavy science with artist flavor–black art to be precise.
Using a PhD in Materials Science, 5 years of cleanroom processing, a hundred thousand dollar budget, and whole lot of time Dr. North developed custom processing techniques to sculpt at this size scale. Because of this odd mix of opportunity, skill and resources Dr. North is the only person on the planet that can create these structures. They’re made of a mix of silicon (what computer chips are made of), silicon dioxide, titanium, titania, and photopolymer.
In the image below, titanium is converted into a nanostructured titania. The process introduces intrinsic stress into the cantilever structures causing it to distort into this lovely shape.
