Acoustic phonons in nanowires with embedded heterostructures

Ayedh, Hussein and Wacker, Andreas LU (2011) In Journal of Nanomaterials 2011.
Abstract (Swedish)
Abstract in Undetermined

Acoustic phonons are studied in finite nanowires based on the elastic continuum model. The phonon dispersion relations are compared for different types of approximations both for pure

nanowires and nanowire heterostructures including cubic and wurtzite materials. We find that

the isotropic approximation highly underestimates the frequency of torsional modes. The impact

of heterostructures on the lowest modes is rather weak and can be described by an average of the

different structure parameters.
