Extreme close-up of tape in a scanning electron microscope. It’s conductive carbon tape, which we use for mounting stuff in the electron microscope, and it’s usually covered in strange craters and textures - I don’t know what purpose those serve. Does make it look like some kind

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
