Résumé

Building two-dimensional lattices in semiconductor quantum-wells offers the prospect to design distinct energy-momentum dispersions, including conical intersections and nondispersive bands. Here, we compare three lithographic patterning methods, e-beam lithography, block copolymer lithography and thermal scanning probe lithography to produce a honeycomb lattice in an In0.53Ga0.47As quantum well. We weigh up the pros and cons of each method to reach lattice constants smaller than 20 nm with a minimum of dispersion in the pore size.
