ABSTRACT:
A method of fabricating a tunable quantum dot apparatus, comprising: forming multi-quantum wells sandwiched substantially between at least two barrier layers; spin coating a non-continuous mask onto at least one of said barrier layers; forming a gate material onto the mask, wherein the non-continuity of the mask substantially prevents formation of a continuous gate material layer; lifting off at least a portion of the gate material; self isolating the gate material; and, forming a top contact onto at least a portion of said barrier layers
