New type of semiconductor may advance low-energy electronics

A research partnership between Penn State and the Massachusetts Institute of Technology (MIT) could enable an improved method to make a new type of semiconductor that is a few atoms thin and interacts with light in an unusual way. This new semiconductor could lead to new computing and communications technologies that use lower amounts of energy than current electronics.

NSF Renews PARADIM REU Program with $621K Grant

By PARADIM News

A program designed to give undergraduate students an introductory summer research experience in materials discovery has been funded through a three-year, $621,000 grant from the National Science Foundation. The grant renews the Research Experiences for Undergraduates (REU) program and leverages the Platform for the Accelerated Realization, Analysis, and Discovery of Interface Materials (PARADIM) - a national user facility dedicated to accelerating the discovery of next-generation materials for electronics.
