Science Gallery at Electric Picnic

Science Gallery goes Nano

Science Gallery NanoLogoOur good friends at CRANN (Centre for Research on Adaptive Nanostructures and Nanodevices) have been playing around with the Science Gallery logo and using a Focused Ion Beam (FIB) they've recreated the logo on a flat diamond surface.

How's it done? The FIB emits Ga+ ions from a liquid metal Gallium well and accelerates them at 30, 000 volts towards a sample. Given their weight, these ions have enough energy to pulverize the atoms on the samples surface that they hit evaporating them into the vacuum. In plain speak: the FIB digs nano-holes into a surface. It's so small that you can only see this with a scanning electron microscope as one nanometer is 10 -9 meter, or a millionth of a millimeter. Too small for us to use this logo in conventional advertising, but pretty interesting nonetheless!!
