The effect of traps on the performance of graphene field-effect transistors

This paper studies the performance degradation of graphene field-effect transistors due to the presence of traps. The mobile charge modulation by gate voltage is degraded because of immobile trapped charges. As a result the current is reduced and the on/off ratio is decreased. Extracted mobility using transconductance method is shown to be underestimated considerably due to the effect of traps.
