Breakdown of the Stokes-Einstein relation in Stillinger-Weber Silicon
Himani Rautela, Shiladitya Sengupta, Vishwas V. Vasisht
We investigate the dynamical properties of liquid and supercooled liquid silicon, modeled using the Stillinger-Weber (SW) potential, to examine the validity of the Stokes-Einstein…
