Prismatic Quantum Heterostructures Synthesized on Molecular‐Beam Epitaxy GaAs Nanowires
Source abstract
Abstract
GaAs nanowires are synthesized by molecular-beam epitaxy (MBE) without using gold as a nucleation seed. The synthesis can be tuned from 1D to 2D by changing the MBE growth conditions. This allows the deposition of quasi 1D quantum wells on the nanometer-wide facets of the nanowires, resulting in a prismatic geometry (see image).

18. To ensure a clean surface the substrates were etched with dilute buffered hydrofluoric acid (HF) for 3 s and then immediately transferred into the growth chamber. To desorb any remnant adsorbed molecules of the surface the wafers were heated to 650 °C for 30 min prior to growth.

26. To obtain cross‐section measurements the nanowires were first transferred onto a silicon substrate and coated with a 100‐nm SiO2layer. The ensemble was then further prepared using traditional X‐TEM methods for thin films.
