Query: Selective-area chemical beam epitaxy of in-plane InAs one-dimensional
  channels grown on InP(001), InP(111)B, and InP(110) surfaces   We report on the selective-area chemical beam epitaxial growth of InAs
in-plane, one-dimensional (1-D) channels using patterned SiO$_{2}$-coated
InP(001), InP(111)B, and InP(110) substrates to establish a scalable platform
for topological superconductor networks. Top-view scanning electron micrographs
show excellent surface selectivity and dependence of major facet planes on the
substrate orientations and ridge directions, and the ratios of the surface
energies of the major facet planes were estimated. Detailed structural
properties and defects in the InAs nanowires (NWs) were characterized by
transmission electron microscopic analysis of cross-sections perpendicular to
the NW ridge direction and along the NW ridge direction. Electrical transport
properties of the InAs NWs were investigated using Hall bars, a field effect
mobility device, a quantum dot, and an Aharonov-Bohm loop device, which reflect
the strong spin-orbit interaction and phase-coherent transport characteristic
in the selectively grown InAs systems. This study demonstrates that
selective-area chemical beam epitaxy is a scalable approach to realize
semiconductor 1-D channel networks with the excellent surface selectivity and
this material system is suitable for quantum transport studies.
