Bandstructure and Contact Resistance of Carbon Nanotubes Deformed by the Metal Contact
Roohollah Hafizi, Jerry Tersoff, Vasili Perebeinos
Capillary and van der Waals forces cause nanotubes to deform or even collapse under metal contacts. Using ab-initio bandstructure calculations, we find that these deformations redu…
First-principles study of MoS and MoSe nanoclusters in the framework of evolutionary algorithm and density functional theory
Zohre Hashemi, Shohreh Rafiezadeh, Roohollah Hafizi +2
Evolutionary algorithm is combined with full-potential ab-initio calculations to investigate conformational space of (MoS) and (MoSe) (n=1-10) nanoclusters and to i…
First-principles structure search for the stable isomers of stoichiometric WS2 nano-clusters
Roohollah Hafizi, S. Javad Hashemifar, Mojtaba Alaei +2
In this paper, we employ evolutionary algorithm along with the full-potential density functional theory (DFT) computations to perform a comprehensive search for the stable structur…
