Abstract :
For the radial boundary force induced in the process, the strain energy distribution and strain tensor components in Ge (110) nanowire (NW) are calculated by finite element method. Based on the strain distribution, we compute valence band structures with different radial forces. As increasing force values, top valence subbands shift downwards. The influence on the corresponding effective masses and density of states are also investigated.
