(Nanowerk News) Sandip Tiwari, a Charles N. Mellowes Professor of Engineering at Cornell University, has been named as the recipient of the 2007 IEEE Cledo Brunetti Award, recognizing his pioneering contributions to nano-crystal memories and quantum-effect devices and their critical role in greatly increasing storage capacities for mobile communications, computing and other applications, while still keeping the devices compact in size. The IEEE is the world’s leading professional association for the advancement of technology.

From his invention of nano-crystal memories to his broad contributions in the emerging field of nanotechnology, Tiwari has repeatedly broken new ground in areas spanning heterostructures, quantum confinement and nano-devices. H is research has had great commercial significance, having paved the way for numerous mobile communications devices, computing and other applications by helping move memory to ever smaller dimensions while preserving low power and maintaining acceptable levels of charge storage. He is also author of the textbook, “Compound Semiconductor Device Physics,” and is the founding editor-in-chief of IEEE Transactions on Nanotechnology, which covers the physical basis and engineering applications of phenomena at the nanoscale level across all areas of science and engineering.

Tiwari’s early research led to several technologies currently in use in compound semiconductors and other device phenomena including electron injection processes in coupled confined systems, frequency limitations of quantum-wire lasers due to gain compression and high-current alloy barrier effects. His past research also opened up the fields of electronics and photonics.

In more recent years, Tiwari has explored power-adaptive, energy-efficient electronics such as small devices and their circuits, three-dimensional integration as well as ideas and technologies that are off-shoots of small structures in other areas. He also has formed the National Nanotechnology Infrastructure Network (NNIN) by bringing together a consortium of universities aimed at furthering nano-scale research.

Born in Ahmedabad, India, Tiwari earned a Bachelor of Technology degree from the Indian Institute of Technology in Kanpur, India in 1976, a Master of Engineering degree from Rensselaer Polytechnic Institute in Troy, N.Y., in 1977 and a doctorate from Cornell University in Ithaca, N.Y., in 1980. An IEEE Fellow, he has previously received the Young Scientist Award of 1991 from the Institute of Physics and the 2003 Distinguished Alumnus Award from the Indian Institute of Technology.
