Two different embedded atom model (EAM) potentials and one bond-order potential (BOP) are compared. A new analytical approach for constructing asymmetrical screw dislocations is presented.bccscrew dislocationdislocation coreempirical potentialstungstenAtomistic simulation of ½<111> screw dislocations in BCC tungstentext::journal::journal article::research article
