Shape and orientation effects on the ballistic phonon thermal properties of ultra-scaled Si nanowires
Shape and orientation effects on the ballistic phonon thermal properties of ultra-scaled Si nanowires
The effect of geometrical confinement, atomic position, and orientation of silicon nanowires (SiNWs) on their thermal properties are investigated using the phonon dispersion obtained using a Modified Valence Force Field (MVFF) model. The specific heat (CĪ½) and the ballistic thermal conductance (Īŗlbal) shows anisotropic variation with changing cross-section shape and ā¦
