Lattice dynamics and electron-phonon coupling in transition-metal diborides
Lattice dynamics and electron-phonon coupling in transition-metal diborides
The phonon density-of-states of transition metal diborides TMB2 with TM = Ti, V, Ta, Nb and Y has been measured using the technique of inelastic neutron scattering. The experimental data are compared with ab initio density functional calculations whereby an excellent agreement is registered. The calculations thus can be used …
