Crystalline Al2O3 on buffered soda-lime glass by e-beam

We report for the first time the successful deposition of a continuous crystalline Al2O3 film on ordinary soda-lime glass via an extremely highly textured MgO buffer layer, using the ordinary electron-beam evaporation method. As a result, a highly crystalline thin-film of silicon may now be deposite...

Description
Summary:We report for the first time the successful deposition of a continuous crystalline Al2O3 film on ordinary soda-lime glass via an extremely highly textured MgO buffer layer, using the ordinary electron-beam evaporation method. As a result, a highly crystalline thin-film of silicon may now be deposited on inexpensive Al2O3 buffered soda-lime glass for cost-effective photovoltaic and other electronic applications. In addition, our results have made possible a new kind of inexpensive and light-weight “sapphire glass” that can be used for display covers for smartphones etc. •Crystalline Al2O3 on ordinary soda-lime glass.•Preliminary step for a novel VLS-TF method.•Extremely highly textured MgO [111] on soda-lime glass.•Immediate applications for solar, semiconductor, and display industries.•Highly cost effective and easily scalable manufacturing technique.
