@article{lowe_eapen_2018, title={Using Space-Time Correlations to Identify Transient Defects}, volume={3}, ISSN={["2059-8521"]}, DOI={10.1557/adv.2018.196}, abstractNote={Atomistic simulations are employed to investigate the dynamical behavior of atoms in cubic silicon carbide (SiC) following a 5 keV radiation knock. Specifically, we have computed the time-resolved van Hove self-correlation function, G_s(r,t), separately for the silicon and carbon sub-lattices. Our goal is to probe the early radiation damage mechanisms using a dynamical methodology. The simulation results show that the carbon atoms engage in a dynamic hopping mechanism as the system recovers from the radiation knock. The silicon atoms, however, exhibit a strikingly different behaviour: the time variation of 4πr^2G_s(r,t) indicates a dynamic tension between the crystalline and disordered regions of the Si sub-lattice. The power-law tail of the 4πr^2G_s(r,t) correlation for silicon atoms suggests a scale-free self-organized critical (SOC) state – a possible precursor to the collapse of the Si sub-lattice.}, number={31}, journal={MRS ADVANCES}, author={Lowe, William and Eapen, Jacob}, year={2018}, pages={1755–1760} }
