Queen's Researcher Leads Team To Discovery That Could End Cracked Smart Devices
A researcher at Queen's University in Belfast has led an international team of scientists to the discovery of a new material, which could bring an end to cracked smartphone and tablet screens.
Dr Elton Santos from Queen's University's School of Mathematics and Physics, has been working with a team of scientists from Stanford University, University of California, California State University and the National Institute for Materials Science in Japan, to create new dynamic hybrid devices that are able to conduct electricity at unprecedented speeds and are light, durable and easy to manufacture in large scale semiconductor plants.
The team found that by combining semiconducting molecules C60 with layered materials, such as graphene and hBN, they could produce a unique material technology, which could revolutionise the concept of smart devices.
The combination works because hBN provides stability, electronic compatibility and isolation charge to graphene while C60 can transform sunlight into electricity. Any smart device made from this combination would benefit from the mix of unique features, which do not exist in materials naturally. This process, which is called van der Waals solids, allows compounds to be brought together and assembled in a pre-defined way.
Dr Elton Santos said: "Our findings show that this new ‘miracle material’ has similar physical properties to Silicon but it has improved chemical stability, lightness and flexibility, which could potentially be used in smart devices and would be much less likely to break.
"The material also could mean that devices use less energy than before because of the device architecture so could have improved battery life and less electric shocks.
"By bringing together scientists from across the globe with expertise in chemistry, physics and materials science we were able to work together and use simulations to predict how all of the materials could function when combined – and ultimately how these could work to help solve every day problems.
"This cutting-edge research is timely and a hot-topic involving key players in the field, which opens a clear international pathway to put Queen’s on the road-map of further outstanding investigations."
