"combined properties of Al and InAs become modified in super-semi sandwiches. At the interface between the Al superconductor and the InAs semiconductor, the proximity effect spills the superconductivity into the semiconductor creating new quantum states there... sending a current alternating billions of times a second through the vicinity of the sandwich, we could make the superconductor's veil partially transparent"
