Fracture patterns at the edge of a broken wafer (broken on purpose, for once). The lighter top layer is silicon, and the darker bottom layer is glass. The glass looks darker than the silicon because it’s a better electrical insulator - the electron beam microscope makes an image by

Microscopic fracture patterns appear clifflike on the edge of one of my samples. This entire view is less than 10 micrometers high, meaning that it covers about a tenth the thickness of a typical human hair. We usually don’t get patterns like these, because we use a special wafer

The crazy-huge mountains of the nanoworld! The strange waves and scallops are what is left of the protective mask I used to shield the semiconductor material below from a high-energy etching plasma. The mask held up to the plasma, although it was probably damaged a bit - and then I

A mini-monument, made of semiconductor laser material. It looks to me a bit like Devil’s Tower. It’s much, much smaller, though. Scaling this little nano-tower (600nm high) to the height of Devil’s Tower (386m high) would be like scaling up an average-sized human (~1.7m) to about
