Abstract Scope |
As a direct consequence of structural disorder, glasses exhibit local property fluctuations and non-affine stimulus response. However, the statistics of glassy disorder have been elusive beyond computational models. This precludes property predictions in analogy to crystalline materials.
Some features of disorder are embedded in the anomalous vibrational properties of glasses; they can readily be probed using a variety of experimental techniques. Most prominently, the so-called boson peak is thought to hold a key to disorder statistics. At the same time, the practical relevance of tailoring glassy disorder is becoming more and more obvious, for example, in the design of glasses with adapted transport properties, mechanical performance or opto-electronic functionality. This talk will discuss some of these aspects from the viewpoint of experimental limits, novel glass formulations, post-processing techniques and ways to access “forbidden” states of glass through non-conventional approaches. |
