Group III-V/group IV epitaxy has recently attracted much interest for applications especially in integrated photonics, or solar energy harvesting devices. For years, the pioneering works of H. Kroemer [1] that successfully identified the key issues, were taken as a reference for the understanding of III-V/Si heteroepitaxy, but recent...

Here, we experimentally and theoretically clarify III-V/Si crystal growth processes. Atomically resolved microscopy shows that monodomain three-dimensional islands are observed at the early stages of AlSb, AlN, and GaP epitaxy on Si, independently of misfit. It is also shown that complete III-V/Si wetting cannot be achieved in most III-V/Si...
