D. A. Ritchie's research focuses on the physics of extremely small electronic and optical devices made from semiconductors, particularly how electrons behave when confined to very thin layers or narrow channels at low temperatures. This work spans quantum transport phenomena (like the fractional quantum Hall effect and single-electron behavior), terahertz-frequency devices and detectors, and quantum light sources such as entangled photon emitters for telecommunications. The research combines fundamental studies of quantum electron behavior with the engineering of practical devices like lasers, detectors, and metamaterials.
