Welcome to Dr Dave Cox's Nanofabrication Page

The pages contained in the site are largely about the work carried out at the University of Surrey and the National Physical Laboratory in the UK in the area of nanofabrication and nanomanipulation. There is also a bit about me, and the work that has been published that I’ve contributed to.

The majority of the devices and structures shown here are made using optical and e-beam lithography, focused ion beam, and in-situ manipulation of nano and micro-scaled objects. Nanofabrication is quite simply fabrication on a nanometer scale. Likewise nanomanipulation is the manipulation of objects and structures on a similar scale. The reason we do this is to exploit the unique properties that can exist in materials and devices when they are this small.

To give an idea of the scale involved, and using examples from nature, the often quoted human hair is about 50 micrometers in diameter, that is fifty-millionths of a meter, about half that diameter is a grain of pollen.

A human red blood cell is about 10 micrometers in diameter.

An E.coli bacterium is two micrometers long, and less than one micrometer in diamter (one millionth of a meter), we commonly work at this scale.

Finally a single strand of DNA is about 2 nanometers in diameter (two billionths of a meter). In our work this is about as small as we go, where we work with carbon nanotubes and other nanowires of similar dimensions.

Below and left are links regarding information about where I work, the tools that I use, the work that I have carried out, plus other links to my youtube site for more light hearted examples.
Hope you enjoy it, contact me if you require any further information about the site. As and when I learn more about XHTML I will update and get a bit snazzier.
