Morphological evolution of a semiconductor surface driven by irradiation-induced anisotropic plastic flow
Tyler P. Evans, Scott A. Norris
While numerous models exist which explain certain aspects of irradiation-induced nanopatterning on semiconductors, a comprehensive theoretical explanation has remained elusive. How…
Fluidity and morphological stability of an amorphous thin film with radiation-induced defect kinetics
Tyler P. Evans, Eden Heyen
It is common to model ion-irradiated amorphous thin films as if they were highly viscous fluids. In such models, one is frequently concerned with the ion-enhanced fluidity, a measu…
Viscous flow model of ion-induced pattern formation: consistency between theory and experiment
Tyler P. Evans, Scott A. Norris
It is known that ion-irradiation can lead surfaces to spontaneously develop patterns with characteristic length scales on the order of only a few nanometers. Pattern formation typi…
Design of resilient structures by randomization and bistability
Debdeep Bhattacharya, Tyler P. Evans, Andrej Cherkaev
This paper examines various ways of improving the impact resilience of protective structures. Such structures' purpose is to dissipate an impact's energy while avoiding cracking an…
