Methods Of Growing Heteroepitaxial Single Crystal Or Large Grained Semiconductor Films And Devices Thereon
A method is disclosed for making semiconductor films from a eutectic alloy comprising a metal and a semiconductor. Through homogeneous nucleation said film is deposited at a deposition temperature on flexible substrates, such as glass. Specifically said film is vapor deposited at a fixed temperature in said deposition temperature where said deposition temperature is above a eutectic temperature of said eutectic alloy and below a temperature at which the substrate softens. Such films could have widespread application in photovoltaic and display technologies.

- 1. A method of making a Vapor-Liquid-Solid (VLS) thin-film semiconductor device, comprising the steps of:
providing a substrate, and vapor depositing a granular semiconductor film onto said substrate, said semiconductor film being deposited out of a eutectic liquid, said eutectic liquid comprising a metal part and a semiconductor material, said metal part deposited onto said substrate before said semiconductor material.
- 16. A thin-film semiconductor device, comprising a flexible glass substrate and a granular semiconductor film deposited using a Vapor-Liquid-Solid technique out of a eutectic liquid.
