The local bond angle distributions show a modest increase in the tetrahedral order upon decreasing the temperature. We also analyze the variation of several dynamic magnitudes and transport properties with temperature, showing a tendency to sustain shear waves for some wavevectors as undercooling is deepened. We compare our orbital-free ab-initio results with the limited experimental data available, as well as with results of other ab-initio simulations.en10.1140/epjst/e2011-01417-0info:eu-repo/semantics/closedAccessElectromagnetic-Levitation TechniqueMolten SiliconPhase-TransitionDensityAn investigation of the local structure and dynamic properties of undercooled liquid silicon using the orbital-free ab-initio molecular dynamics methodArticle19614552Q2WOS:0002910495000062-s2.0-79957968806Q2
