Yarub, Al - Douri Baltache, H.b yarub@unimap.edu.my Effective mass FP-LMTO Half-Heusler alloys Structural properties Link to publisher's homepage at http://www.elsevier.com/ We have performed ab-initio self-consistent calculations using the full-potential linear muffin-tin orbital (FP-LMTO) method to investigate the structural and the electronic properties of some half-Heusler alloys. The local density and generalized gradient approximations were used for NiTiSn and CoVSn alloys. Due to the metallic characters of both NiTiSb and CoVSb compounds, the local spin density approximation was used. Lattice constants, bulk moduli, and the pressure derivatives of the bulk moduli are calculated, band structure and density of states are drawn and effective masses are investigated. To our knowledge this is the first quantitative theoretical prediction of the effective masses for the investigated compounds and still awaits experimental confirmations. The obtained results are agreed well with the other published values. 2013-06-24T05:02:46Z 2013-06-24T05:02:46Z 2013-04 Article Optik, vol. 124(7), 2013, pages 570-574 0030-4026 http://www.sciencedirect.com/science/article/pii/S0030402612000629 http://hdl.handle.net/123456789/26007 Elsevier GmbH. |
