Abstract

The concepts of resonant tunneling and superlattices were first developed by Esaki and Tsu. What started with the new physics of the Esaki tunnel diode has matured into nanoscale engineering of semiconductors superlattices to create whole synthetic band structures. While working at Thomson CSF in France, Manijeh Razeghi went on to develop the metal-organic chemical vapor deposition (MOCVD) and molecular beam epitaxy growth of superlattice material as reported in my seminal volumes of The MOCVD Challenge. After years of considerable effort to bring this technology to maturity, we now see the results of this formidable new science in almost every electronic and photonic device that we encounter. Among the most successful triumphs are the type-II superlattice photodetectors and quantum cascade lasers - these technologies have demonstrated the beauty of turning fundamental concepts into practical devices, thanks to advanced growth technologies. This enables us to design and realize compact devices capable of mimicking or even exceeding nature. Using superlattice to pioneer the development of quantum systems is driving the research work at the Center for Quantum Devices.
