Understanding the electronic properties of ultrathin operational devices

PhD defence, Tuesday 31 January, Alfred John Henry Jones

Alfred John Henry

During their studies, Alfred researched a selection of two-dimensional materials, including graphene, a material that is only one atom thick. These materials exhibit extraordinary new properties, and may be useful for next-generation electronic devices, for example in computer chips. By combining different materials together in different ways, new properties can emerge. Alfred looked at how the electrons in these materials behaved when they were subject to a current or electric potential, as they would be when operating as devices.

These new findings contribute to better understanding of how the electronic properties of two-dimensional materials can be modified, which will allow for the designing of new, even smaller devices.

The PhD degree was completed at the Department of Physics and Astronomy, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
