WebSep 11, 2024 · This section deals with the geometry of crystaline systems. These could describe how metal atoms pack when they form metallic solids, or how ions pack when they form ionic crystals. We will look at the ionic structures in the next section, and here focus on the generic unit cell and it's application to metallic structures. http://www-personal.umich.edu/~malloryd/haoyang.pdf dac with wifi streaming
