  • Title: Theory of MOCVD Growth of III-V Nanowires on Patterned Substrates.
    Author: Dubrovskii VG.
    Journal: Nanomaterials (Basel); 2022 Jul 30; 12(15):. PubMed ID: 35957064.
    Abstract:
    An analytic model for III-V nanowire growth by metal organic chemical vapor deposition (MOCVD) in regular arrays on patterned substrates is presented. The model accounts for some new features that, to the author's knowledge, have not yet been considered. It is shown that MOCVD growth is influenced by an additional current into the nanowires originating from group III atoms reflected from an inert substrate and the upper limit for the group III current per nanowire given by the total group III flow and the array pitch. The model fits the data on the growth kinetics of Au-catalyzed and catalyst-free III-V nanowires quite well and should be useful for understanding and controlling the MOCVD nanowire growth in general.
