Abstract:
1. A process for making a stacked structure of planes of islands of a first semiconducting material encapsulated in a second semiconducting material on a substrate, the process comprising: alternately depositing planes of islands of a first semiconducting material and encapsulation layers of a second semiconducting material; wherein: the planes of islands of the first semiconducting material are made at an optimum growth temperature and at an optimum precursor gas partial pressure for obtaining a stacked structure having optical properties enabling production of optoelectronic components to interconnect integrated circuits; the stacked structure is made on a sacrificial plane of islands of a third semiconducting material encapsulated in a fourth semiconducting material; the islands of the sacrificial plane are made under growth conditions resulting in high densities of small islands, the conditions including at least one of a temperature below the optimum growth temperature and a precursor gas partial pressure greater than the optimum partial pressure.
