Average dimensions and number density of the NWs and 3D islands grown at different deposition times
Deposition time (min) Length of NWs (nm) Width of NWs (nm) Height of NWs (nm) Density of NWs (number/μm2) Size of 3D islands (nm) Height of 3D islands (nm) Density of 3D islands (number/μm2)
5 176.3 18.9 2.9 31 18.0 5.2 49
10 271.5 17.2 3.5 21 24.7 7.2 46
25 281.2 16.9 4.2 25 27.0 7.3 65
50 261.4 16.5 5.1 20 35.9 10.3 70

The growth temperature and deposition rate for each deposition were kept at 550°C and 0.2 ML/min, respectively.
