In strontium titanate, a stable two-dimensional electron gas was created, in a thin layer just below the surface. The electrons in this gas can occupy very different quantum states with very different properties. This new material is a remarkable new instrument for designing electronics and possibly using exotic material effects such as superconductivity.
