Newton’s rings put on a microscopic show. This is a microscope image, about 20x, of some bright bands of color that appeared on the surface of one of my samples. They’re formed from a colorless film of residue left behind after some IPA dried on my sample -

Someone asked me yesterday how big my samples are, and what it all looks like. This is a zoomed-out view (only 90x!) showing a nearly edge-on view of one of my samples, sitting on a cratered sea of carbon tape. It’s so zoomed-out that I almost feel embarrassed asking

This entire view would fit easily inside a single cell. The “lake” is a crater with glass at the bottom - being an insulator, glass tends to build up charge that deflects the electron beam my microscope fires at the sample, so very little bounces back… it appears dark. The

Multicolored marbled patterns! Ladies and Gentlemen, I give you an unsuccessful attempt to clean tape scum off a delicate semiconductor surface. The carbon tape I use in the scanning electron microscope, which looks so cool in the microscope and improves my image quality so much, leaves scum behind, as it

The lace ship. This is some sort of dust that landed on my sample before etching - I do try to clean dust off, but I don’t get everything removed. This particular sample had a few of these airy, lacy dust particles - I’m not sure what they

I posted a picture of the jagged broken edge of my sample the other day. Now here’s the same spot under the electron microscope. This view’s looking from the side, so you see all the detail of the dark edge where the silicon snapped. This far zoomed out,

Nom nom. Apparently, my nanostructures are tasty. This little guy is only about 1 micrometer high, less than 1/100 the thickness of a typical piece of paper. And the guy appears to have latched on to one of my little structures - ruining it, I might add. I guess

Here’s the jagged edge where my sample broke. I blame the carbon tape, which is usually my friend, a nice way to get rid of those pesky extra electrons, and a way to stop my sample from falling off the holder in the electron microscope. Except this time, the

Islands! Actually, it’s Newton’s Rings again, a rainbow effect caused when white light shines on really thin films of transparent stuff. In this case, I don’t know what the transparent stuff is. The material beneath is semiconductor laser material. I was trying to clean it with alcohol,

Welcome to Mount Gloop. I don’t know what this mountain is made of - like most of the naturalistic landforms I discover, it’s not supposed to be there. It’s probably some sort of residue or gunk. It rises out of a plane of semiconductor laser material. Those
