| Citation | Distinguished for work on the theory of semiconductors, and for his contributions to the developing field of superlattice devices. Dr Kelly's early research on semiconductor surfaces broadened to cover amorphous semiconductors and amorphous metals, and this in turn led to techniques for making stable contacts on devices made from compound semiconductors. Parallel research on inversion layers on Silicon surfaces was applied to Si MOS devices, and was his introduction to devices exploiting two dimensional conduction. Experience in this field made Dr Kelly well qualified for leading an industrial research team in the rapidly expanding topic of superlattices and low dimensional structures. His publication record over the last three years testifies to his success. He has discovered two new effects, superlattice tunnelling negative resistance and enhanced superlattice photoconductivity as well as making important contributions to the theory of photon transport in wires as thin as 100A. His personal leadership of a young interdisciplinary team has been an important factor in the resurgence of UK semiconductor device physics. |
