Two-dimensional materials are vital for the type of semiconductors that will push the future of electronic devices and energy-efficient lighting, but they are a challenge to make. They must have very few defects, difficult given their very small, nano-level size.

Silicon has been king for a long time in computer technology. It is the namesake for America’s technology hub, Silicon Valley. However, silicon is nearing its limit as an effective semiconductor material.
In some ways, Mauricio Terrones is a gardener. An Evan Pugh University Professor and The Penn State Verne M. Willaman Professor of Physics, Terrones does not grow flowers or vegetables, but instead, one- or few-atom-thick two-dimensional (2D) materials. Specifically, creating materials with specific properties. The first 2D material ever created was graphene, and Terrones was a pioneer in developing 2D materials beyond graphene such as molybdenum disulfide (MoS2) and Tungsten disulfide (WS2). These are layered 2D materials, monolayered, bi-layered, tri-layered or more.

Mauricio Terrones, Evan Pugh University Professor and Verne M. Willaman Professor of Physics, and professor of chemistry and of material science and engineering, has been named the new George A. and Margaret M. Downsbrough Head of the Department of Physics at Penn State, effective July 1. Terrones succeeds Nitin Samarth, who has served as head of the department since 2011.

UNIVERSITY PARK, Pa. – Advances in computing power over the decades have come thanks in part to our ability to make smaller and smaller transistors, a building block of electronic devices, but we are nearing the limit of the silicon materials typically used. A new technique for creating 2D oxide materials may pave the way for future high-speed electronics, according to an international team of scientists.

When used as wearable medical devices, stretchy, flexible gas sensors can identify health conditions or issues by detecting oxygen or carbon dioxide levels in the breath or sweat. They also are useful for monitoring air quality in indoor or outdoor environments by detecting gas, biomolecules and chemicals. But manufacturing the devices, which are created using nanomaterials, can be a challenge.

UNIVERSITY PARK, Pa. - Sometimes friction is good, such the friction between a road and a car’s tires to prevent the vehicle from skidding. But sometimes friction is bad – if you did not put oil in that very same car, there would be so much friction in the bearings of the engine the car could not operate.
