| Biography | Tim Sands received his Ph.D. in Materials Science at the University of California, Berkeley in 1984. He joined the Purdue faculty in the fall of 2002 after nine years as a faculty member of the Department of Materials Science & Engineering at Berkeley. While at Berkeley, he served as the Chair of the Applied Science & Technology (AS&T) graduate group (97-99). From 1984 to 1993, Sands was a Member of Technical Staff, a District Manager, and a research group Director at Bell Communications Research (Bellcore) in Red Bank, NJ. He has published over 200 papers and has been granted 11 patents in the areas of metal/semiconductor contacts, heteroepitaxy, thermoelectric materials, ferroelectric and piezoelectric materials and devices, semiconductor nanostructures, laser processing and heterogeneous integration. Among the most significant of his scientific and technical contributions are i) the understanding of the interface reactions leading to low-resistance, shallow and thermally stable ohmic contacts to compound semiconductors; ii) demonstration of the first stable and epitaxial metal/III-V heterostructures; iii) transfer of the Laser Lift-off process for GaN LED packaging, for which he was a co-inventor, to industry; and iv) leadership of the team that fabricated the first monolithic fluorescence detection microsystems. His present research efforts are directed toward the development of novel nanocomposite materials for applications in solid-state lighting, direct conversion of heat to electrical power, and thermoelectric refrigeration (see https://engineering.purdue.edu/MSE/Turner for more information). Dr. Sands is a recipient of the Materials Research Society (MRS) Von Hippel Award for Graduate Student Research and the Robert Lansing Hardy Gold Medal (The Minerals, Metals and Materials Society). He has served as a Councilor for MRS ('97-'99), as Co-chair for the 1994 Fall MRS Meeting, and as the Chair of the Electronic Materials Committee ('95-'97). Professor Sands is presently the Basil S. Turner Professor of Engineering and a member of the Birck Nanotechnology Center, with joint appointments in the Schools of Materials Engineering and Electrical & Computer Engineering at Purdue. |

Thermoelectric effects are based on the difference between the average energy of the conduction electrons (or holes) and the Fermi energy. A thermoelectric material can be configured into a device for solid-state refrigeration or electrical power generation.
