Craig S. Lent
The Frank M. Freimann Professor of Engineering
The transistor is the fundamental building block of modern electronics systems; today’s computing devices contain transistors made of silicon, which has a high energy output. Too high, actually—meaning that if your laptop gets any faster or smaller, it may very well become too hot to hold in your lap.
As the computer industry scrambles to create the next-generation computer, Craig Lent’s technology is a leading contender to replace the silicon transistor. His atomically scaled device is based on the Quantum-dot-Cellular Automata (QCA), a new transistor-less paradigm that Lent invented with his Notre Dame colleague and fellow Freimann Professor Wolfgang Porod.
A member of the American Physical Society and the recipient of multiple teaching awards, Lent belongs to a group of distinguished scholars who have helped to make Notre Dame one of the world’s premier centers for the study of nano science and technology.
This professorship was established in 2000, with earnings from a gift of the Freimann Charitable Trust, made in honor of Frank Freimann, a pioneer of the electronics industry and former chief executive officer of Magnavox. There are 11 Freimann chairs at Notre Dame, all in engineering and physics.
