Abstract
In this work we describe a proposal for a graphene-based nanostructure
that modulates electric current even in the absence of a gap in the band
structure. The device consists of a graphene p-n junction that acts as a
Veselago lens that focuses ballistic electrons on the output lead.
Applying external (electric and magnetic) fields changes the position of
the output focus, reducing the transmission. Such device can be applied
to low power field effect transistors, which can benefit from graphene's
high electronic mobility.
