Dust again! One of the amazingly varied forms that a single speck of dust can take - they turn from specks to angular mountains, billowing sails, or fluffy clouds. This one’s darker, smoother, and sharper than most… my guess would be that it’s maybe a microscopic shard of

Nanosilverfish? Someone asked me to post a picture of what one of my nanosamples should look like - one that doesn’t have nanofluff or nanozombies or other weird etching/dust problems. The reason I haven’t posted one before is that they look kinda boring - when everything goes

Nano Boba Fett? This is an artifact made of semiconductor laser material, that appeared during a process meant to etch all the laser material away. Probably it was formed by a speck of dust landing in that spot and protecting the material underneath from the etching plasma… the remnants of

A microscope image of a beat-up-looking sample that was abandoned in one of our storage boxes. It looks like maybe it used to have some kind of coating on it, which has deteriorated, or maybe the coating never came out well in the first place, which would be why it

Plasma in a box! We use this machine to etch silicon by blasting it with high-energy plasma, and the machine’s makers were kind enough to include a little viewport in the side so you can look in and see the plasma. It’s this pretty glowing blue-violet color… one

Nature repeats itself on a small scale - These mesas and plateaus are only about 500 nanometers high… if you stacked 2,000 of them on top of each other, they’d just be a millimeter high. How did this happen? The entire landscape is made of laser material, which

Thin-film effects, viewed under a microscope, imitate the night sky. What you see here is a flat surface that has a few defects on it (probably pieces of dust), covered with a thin, transparent film. According to the thickness of the film, you get different colors reflected back - this

Nanozombies! These people-shaped nanopillars were formed by accident while I was etching away laser material to make the long wall at the left of the picture. They creeped me out a little until someone pointed out to me in my last picture [http://tmblr.co/ZP7VLssWK9yZ] that they look like

I have somehow created nanopeople. Their heads are made of laser material and their bodies are made of silicon, which means there’s a remote chance that some of them could be lasers. They’re each so small (300nm high) that a normal bacterium would appear to them like a

A “perfectly clean” surface… This sample looked clean and shiny when I held it up to the light - I had cleaned it several times in harsh solvents like acetone, and even blasted it with high-energy plasma for a good ten minutes. Under the electron microscope, I learned the real
