FIG. 1.

Top views of relaxed structures for ZnO nanowires with different radii. We label these nanowires as wire-A, wire-B, wire-C, and wire-D.

Band gap of ZnO nanowires as a function of strain .

Image of FIG. 3.
FIG. 3.

Band structures of (a) wire-B and (b) wire-C under strains of , −2%, −4%, and −6%. The two arrows in leftmost panels represent the transitions corresponding to peaks and in spectrum shown in Fig. 5.

FIG. 4.

Charge densities of states (a) and (b). The upper panels show the top views and the lower panels show the side views.

Image of FIG. 5.
FIG. 5.

Imaginary part of dielectric functions (polarization parallel to the nanowire axis) for (a) wire-A, (b) wire-B, (c) wire-C, and (d) wire-D under different strains.
