Paper Abstract

Semiconductor surfaces develop orientation dependent morphologies during growth that can be used for fabrication of nanostructured materials. We have applied RHEED techniques to study during MBE the nanometer-scale morphologies on non-(001)-oriented GaAs surfaces and their evolution during heterogeneous deposition of AlAs. In particular, the growth behavior of the GaAs(311)Ga surface enables a controlled generation of an ordered surface corrugation. We report on two new methods for a direct synthesis of 1D structures that take advantage of an in- situ lateral patterning of the GaAs substrate: the growth of corrugated GaAs/AlAs heterostructures on the GaAs(311)Ga surface and the synthesis of doping wires by the combination lattice step growth on vicinal GaAs(001) surfaces with planar doping.
