A robust algorithm to get the chemical potential of the particle reservoirs for the self consistent full 2D Schrodinger-Poisson solver is proposed. Using this algorithm we study the effect of junction depth on ballistic current. Simulation results show that shallow junctions come with much better on to off current ratio while it keeps the on-state transconductance at the same level as the deeper junction device.
