Geballe Receives Von Hippel Award

"In récognition of his ingenious use of chemical principles to synthesize novel materials of technological importance, his careful experiments on a wide range of materials to illuminate fundamental materials properties and behavior, and his leadership in helping to formulate the modem concepts of materials science through his consistent and strong emphasis on interdisciplinarity as a scientist, teacher, and administrator."
Théodore H. Geballe
Théodore H. Geballe has been selected as the récipient of the 1991 Von Hippel Award of the Materials Research Society "in récognition of his ingenious use of chemical principles to synthesize novel materials of technological importance, his careful experiments on a wide range of materials to Ûluminate fundamental materials properties and behavior, and his leadership in helping to formulate the modem concepts of materials science through his consistent and strong emphasis on interdisciplinarity as a scientist, teacher, and administrator." Geballe has been devoted to the synthesis of new materials in areas of potential technological significance and to understanding novel physical properties, particularly in the areas of semiconduction and superconduction. He has effectively combined disciplines of chemistry and physics and helped shape the évolution of materials science. He has patiently insisted that the synthesis of new materials, the détermination

of their physical properties and the theoretical interprétation of thèse properties are most effectively done as part of a continuous "feedback loop," not separately. Based on this point of view, he established a school of materials physics within the Department of Applied Physics at Stanford University. This school is regarded by many as a model of multidisciplinary research. He has been an effective teacher of solid-state physics for over 20 years and has produced a séries of outstanding graduate students who truly understand and practice interdisciplinary materials research. Geballe's early work in the 1950s centered on transport in semiconductors (Ge and Si). His work of this period on conduction, piezoresistance, phonon drag, thermal conduction, and impurity hopping conduction, is considered among the best ever done on thèse topics. He is widely known for his many contributions to superconductivity. His work with Bernd T. Matthias on the A15 dass of superconductors included discovering Nb3Sn superconducting at 18K, the record at the rime. This material became of great technological importance for superconducting magnets. Later Geballe and Matthias raised the critical température to over 20KwithNb 3 (AlGe). His work led to the development of a technologically important class of superconductors based on intercalated compounds (layered transition métal dichalcogenides). He demonstrated enormous critical field anisotropy, a forerunner of effects in récent high Tc superconductors. At Stanford, his group was the first to produce thin films of the high Tc materials, producing them within a
