## Caption

The element geranium is primarily used to make transistors for semiconductors. Here, a colorized scanning electron micrograph captures a cube of germanium attached to a membrane; the four skinny light blue rectangles around the cube are tiny refrigerators that keep the temperature of the cube and membrane down to a few hundred thousandths of a degree above absolute zero.
