Loren Pfeiffer, a senior research scholar in the Department of Electrical Engineering, is perhaps the world's master at growing ultra-pure semiconductors made of gallium arsenide and aluminum gallium arsenide, which allow unprecedented studies of the quantum mechanical interactions of electrons confined in semiconductors. Such studies are relevant for understanding how a quantum computer might operate. In this video, he gives a tour of a new machine for molecular beam epitaxy, which is key to the next generation of these materials. The machine produces the best internal vacuum anywhere on the planet.
