Size-dependent contact angle of Ga droplets on GaAs
We investigate the size and shape dispersion of Ga droplets on GaAs. The contact angle of droplets decreases with decreasing droplet diameter below 40 nm, while it is almost constant for diameter larger than 40 nm. The morphological change of droplets is analyzed in terms of the thermodynamic model including surface and edge energies. (c) 2013 Elsevier B.V. All rights reserved.
