In some examples, a method for manufacturing a solid state device comprises forming a first layer of the solid state device; forming a conductive layer of the solid state device above the first layer, the conductive layer having an access pad formed on an end of the conductive layer; applying a voltage to the conductive layer using the access pad, the voltage forming an electric field in an area of the first layer beneath the conductive layer; and completing manufacture of the solid state device after applying the voltage.
