Liquid polymorphism occurs when a single material has multiple structurally unique liquid phases. Water was the first substance suggested to exhibit multiple liquid phases, a number of monatomic semiconductors and metals have been found to exhibit similar characteristics since then. A better understanding of the liquid-liquid phase transition is needed to tackle problems in glass sciences, it is also relevant to geophysical studies of the Earth's core and mantle and has applications in nanotechnology.140 pagesenCopyright 2015 Adam CadienMaterials ScienceCondensed matter physicsComputer scienceDiffractionDynamicsLiquidPolyamorphismSimulationStructureDissertation
