From: Nucleation of Ga droplets self-assembly on GaAs(111)A substrates
(a) The temperature density dependence of DE GaAs islands grown on GaAs(111)A substrate (red points). The green star indicates the island density of the sample T2b. The nucleation activation energy, \(E_{a}~=~1.13\pm 0.13~\hbox {eV}\). (b) The temperature dependence of a mean size of Voronoi cells. The activation energy \(E_{a}\), calculated from this method, equals 1.13±0.23 eV. The temperature error bar for both graphs is \(\pm 5\,^{\circ }\hbox {C}\).
