| contents | In this work, we present the monolithic integration of GaAsP and GaInP islands, selectively grown on a CMOS-compatible Si nanotip wafer using gas-source molecular beam epitaxy via a nanoheteroepitaxy approach. These alloys span a wide electronic bandgap range, from infrared to green; making them highly attractive for optoelectronic applications in silicon photonics. In addition, the nanoheteroepitaxy method enables the growth of various alloy combinations without the need for a lattice-matched substrate. We discuss the epitaxial challenges involved, particularly the balance between growth selectivity and alloy miscibility. Despite these challenges, our work demonstrates a promising and scalable route toward tunable light sources and detectors monolithically integrated on silicon, contributing to the development of compact and efficient photonic components for next-generation silicon-based technologies. |
