Even when working in the cleanroom, a little dust is hard to avoid. This is a gallery of electron microscope pictures of dust specks I’ve encountered while making nanoscale devices in the UCSD Nano3 cleanrooms. Dust is made of a variety of materials - dead skin cells, tiny bits

I found an area of strange mesa-like structures on one of my samples - near this spot, the sample broke, scattering tiny fragments of glass and laser material across that part of the sample’s surface. After I used high-energy plasma to etch most of the laser material away, the

Nanosouffle? This piece of dust appears to have partially deflated. I’m not sure if it really did crumple, or if it’s just a trick of the angle. The light-colored platform it’s sitting on is all semiconductor laser material, that the dust protected from the high-energy plasma that

Closeup of artificial opal, formed on fragments of microscope slides by drying little plastic beads. Everywhere that the beads happened to assemble themselves into regular arrays as they dried, you get iridescent rainbow colors - the “fire” of opal. The rainbow iridescence comes from the interference of light waves as

This is a bit of clear rubbery silicone with a gold-coated hologram on the top. The patterns are little microchannels where liquid can flow across the surface of the silicone; the larger round areas are where hollow needles can be poked in from the other side of the silicone to
