FIG. 1.

Schematic illustrating the various parameters used in developing the model in regime A, i.e., pure axial growth. The dark squares represent adatoms that impinge directly on the various surfaces: (1) on the seed particle, (2) on the sidewall surface, and (3) on the substrate surface. The dotted line arrows represent the path of the adatoms for incorporation at the axial growth interface.

FIG. 2.

Evolution of the shell height as a result of step-mediated growth. Adatoms from the upper layers do not contribute, and are reflected at the step edge (E-S barrier).

FIG. 3.

Cross-sectional SEM micrographs illustrating the morphology and size of GaAs NWs after (a) 180, (b) 600, (c) 1200, (d) 1800, and (e) 3600 s of growth. The growth temperature was , the V/III flux ratio , and the nominal 2D growth rate 0.28 nm/s.

Image of FIG. 4.
FIG. 4.

Evolution of the GaAs NW height as a function of: (a) the growth duration (for the case ) and (b) the NW diameter in regime A for and various values of and . The data points in (a) are experimental measurements for NWs having a diameter , with the error bars corresponding to one standard deviation. Each point in (b) corresponds to a single NW measurement.

FIG. 5.

Evolution of the GaAs NW height (a) and diameter (b), as a function of the growth duration, for NWs with initial diameter . The error bars correspond to one standard deviation. The various curves are fits to the data based on the proposed model. Four sets of parameters were used for regime B, illustrating the effect of varying and when is kept constant at 1450 s.

FIG. 6.

Evolution of the InAs NW height as a function of the growth duration (for the case ) in regime A for and various values of and . The data points are experimental measurements retrieved from Ref. 26, with the error bars corresponding to one standard deviation.

FIG. 7.

Evolution of the InAs NW height (a) and diameter (b), as a function of the growth duration, for NWs with initial diameter . The data points are experimental measurements retrieved from Ref. 26, with the error bars corresponding to one standard deviation. The various curves are fits to the data based on the proposed model ( in nm, in nm/s).
