The nucleation of islands during Stranski-Krastanov growth of CuCl on
MgO(001) is studied by molecular beam epitaxy and atomic force microsc
opy. The dependence of island density (N) on deposition flux (R) is an
alyzed using the rate equation, for the first time, for a compound-mat
erial growth system in which the impinging particles are ionic molecul
es. The scaling of N similar to R0.5 +/- 0.1 observed at growth temper
atures of 293, 313 and 333 K indicates a critical nucleus size of 2 to
3, leading to the smallest stable island of (Cu3Cl3)(n) (n = 3-4). (C
