US patent (12/774,465) titled "Methods of Growing Heteroepitaxial Single Crystal or Large Grained Semiconductor Films and Devices Thereon" discloses a modified Vapor-liquid-solid (VLS) thin-film (TF) growth technique that for the first time allows for low temperature deposition of exceptionally high quality semiconductor films from a variety of materials such as silicon, germanium, and GaN, on inexpensive substrates.

The cost-effective nanowire-like but thin-film growth process involving eutectic alloys is very well suited for large-scale industrial applications and can be carried out using common deposition processes currently used in various industries, such as e-beam, CVD, etc.
