Pseudomorphic virtual GaP/Si substrates are attractive for III/V-on-Si integration for microelectronics, photovoltaics, and water-splitting. The heterointerface is of particular interest since its atomic and electronic structure highly impacts crystal quality. Well-ordered interfaces are desirable but the formation of polar-on-nonpolar heterointerfaces is not yet fully understood. It is instructive to control each of the three steps (i) Si surface formation, (ii) III/V nucleation, and (iii) III/V layer growth individually in situ, which largely benefits from complementary surface science techniques as well as density functional theory (DFT). Here, we will highlight how such a combination enables specific metalorganic vapor phase (MOVPE) preparation of virtual substrates for both (100) and (111) orientation.
