Small scale lateral superlattices in two-dimensional electron gases prepared by diblock copolymer masks
A poly(styrene-block-methylmethacrylate) diblock copolymer in the hexagonal cylindrical phase has been used as a mask for preparing a periodic gate on top of a GaAs / Al x Ga 1 − x As heterostructure. A superlattice period of 43 nm could be imposed on the two-dimensional electron gas. Transport meas...
