Abstract

Recent progress in the fabrication of GaAs/AlGaAs low-dimensional structures by cleaved edge overgrowth (CEO) — a molecular beam growth technique that involves one or two regrowth steps on the sidewalls of an in situ cleaved layer structure — is reviewed. Ballistic electron transport in modulation-doped quantum wires prepared in this way is characterized by pronounced quantization of the ...
