Unlike graphene, they have a direct band gap, meaning that their valance bands (the outermost electron shells of atoms) are directly aligned with the conduction band (the electron shell adjacent ...

Scientists are investigating how structures made from several layers of graphene stack up in terms of their fundamental physics and their potential as reconfigurable semiconductors for advanced ...

Techniques for Band Gap Engineering vary, including doping, the introduction of impurities into a semiconductor to alter its electrical properties; strain engineering, where stress is applied to ...

University of Texas at Dallas scientists are investigating how structures made from several layers of graphene stack up in terms of their fundamental ...

Defects in two-dimensional materials (such as an atom-thick sheet of graphene) can dramatically ... Our simulations bridge this gap, allowing us to track the rippling dynamics in detail and ...
