Bandgap Manipulation of Armchair Graphene nanoribbon
Papers | 01 Sep 2020 | Contributor(s):: Lance Fernandes
Bandgap Manipulation is very important for various applications. Optical Devices need smaller Bandgap where as Diode's need larger Bandgap. Armchair graphene Nanoribbon (AGNR) has a special property where if the numbers of atoms are multiple of three or multiple of three plus one, they are...
