Title: Atomic Structure of an Amorphous/Crystal Interface

Abstract

In this study, the authors report atomic-resolution images that illustrate the transition from a crystalline Si{sub 3}N{sub 4} grain across the interface into an amorphous Lu-Si-Mg-N-O glassy phase. The interface is not atomically abrupt, but is comprised of sub-nanometer-scale ordered regions that resemble a LuN-like structure. These ordered clusters bind to the prismatic surface of the Si{sub 3}N{sub 4} grains at specific low energy positions for Lu adsorption as predicted by first-principles calculations. The ordered regions are filamentary in nature, extending for at least two atomic layers into the amorphous pockets at multigrain junctions before disappearing.
