Homoepitaxy is a kind of epitaxy performed with only one material, in which a crystalline film is grown on a substrate or film of the same material. This technology is often used to grow a film which is more pure than the substrate and to fabricate layers having different doping levels. In academic literature, homoepitaxy is often abbreviated to "homoepi". Homotopotaxy is a process similar to homoepitaxy except that the thin-film growth is not limited … WebFeb 2, 2024 · In conclusion, we have successfully demonstrated a wafer-scale, layer-controlled organic single-crystalline film composed of only a few molecular layers and achieved a sufficiently high carrier mobility of 13 cm 2 V −1 s −1 together with an extremely low contact resistance of 46.9 ohm·cm.
