Enhanced thermopower of graphene films with oxygen plasma treatment
In this work, we show that the maximum thermopower of few layers graphene (FLG) films could be greatly enhanced up to ∼700 μV/K after oxygen plasma treatment. The electrical conductivities of these plasma treated FLG films ...
Power factor enhancement for few-layered graphene films by molecular attachments
In this work, we prepared few-layered graphene (FLG) films and investigated their thermoelectric properties. It was found that pristine FLG films showed a low thermopower of ~40 μV/K. We further processed these FLG films ...
