A novel split gate design to study interaction effects in quantum wires

A new concept to form ballistic quantum wires based on a triple split gate structure on top of a GaAs/AlGaAs heterostructure is presented. Due to the flexibility in the design we propose this method, which would allow one to check the predictions of the Luttinger liquid model. The current–voltage characteristic of an embedded tunneling barrier in a View the MathML source long ballistic quantum wire is also addressed in some detail.
