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.

Like little colorful jewels, these microscopic spots of color are probably the remnants of a thin coating that once covered this sample. The spots get their color not from the usual pigments or dyes that color things like flower petals and paint, but from another phenomenon, called structural color, which

There aren’t any dyes or pigments in this photo - all this color is due to the wave nature of light. Thin transparent films produce rainbows, when light waves bouncing off the top and the bottom of the film interfere with each other on the way back. It’s the

Coastline of the land of monuments… tiny monuments. Each of them would fit easily inside a single human cell. They’re formed out of semiconductor, and are the result of what we call micromasking: tiny bits of debris landed on the semiconductor before the etching step, and protected the semiconductor
