On-demand conductivity for graphene nanoribbons

Physicists have devised a theoretical model to tune the conductivity of graphene zigzag nanoribbons using ultra-short pulses. Physicists have, for the first time, explored in detail the time evolution of the conductivity, as well as other quantum-level electron transport characteristics, of a graphene device subjected to periodic ultra-short pulses. To date, the majority of graphene studies have considered the dependency of transport properties on the characteristics of the external pulses, such as field strength, period or frequency.
