  "abstract": "We probe quantum Hall effect in a tunable 1-D lateral superlattice (SL) in graphene created using electrostatic gates. We create strong local electric field at the interface of regions of different charge densities. Crossed electric and magnetic fields modify the spectrum and wavefunction of the Landau Levels (LLs) which is reflected in magnetotransport. In the region of copropagating electrons and holes at the interface, the electric field is high enough to cause departure from full equilibration picture. This ability to modify LL wavefunctions with electric field is unique to graphene and cannot be seen in 2DEG.",
