Abstract

The current LIGO optics employ ion-beam–deposited amorphous oxide coatings. Amorphous oxides, such as amorphous alumina (Al2O3), are also among the leading candidate materials to make improved-performance coatings. In this talk, I will present computational results examining how deposition conditions—particularly substrate temperature—affect the atomic structure of amorphous alumina. I will also discuss whether these simulations indicate the feasibility of achieving ultra–low–mechanical-loss coatings through deposition at elevated substrate temperatures.
