| Biography | S. James Allen, currently member of the UCSB Physics Department, received a Ph.D. degree in electrical engineering from M.I.T. in 1965. Prior to appointment at UCSB, he had been a member of technical staff at Bell Labs, during which time he took a brief leave at the Royal School of Mines, Imperial College. Later he joined Bellcore, as Research Manager of Solid State Physics Research. His research has explored transport and terahertz excitations in semiconductor nano-structures, hot-electron dynamics, high temperature superconductivity, magnetism, superionic conductors, metal physics and clathrate inclusion compounds. Current research focuses on terahertz dynamics in semiconductor quantum structures far from equilibrium, Bloch oscillators, novel terahertz detectors and terahertz circular dichroism and dynamics of bio-polymers. |

The concepts of Bloch oscillation and Zener breakdown are fundamental to electron motion in periodic potentials and were described in the earliest theoretical developments of electron transport in solids. But only in the past 10 years have experiments clearly demonstrated various aspects of Bloch …
