FIG. 1.

Schematic representation of the hut and the truncated-hut structures used to observe the evolution of the strain energy as the aspect ratio changes.

FIG. 2.

The relationship between the normalized strain energy density and the aspect ratio for the hut structures shown in Fig. 1.

Image of FIG. 3.
FIG. 3.

The strain energy evolution of the {105} faceted truncated-hut structures when the aspect ratio changes under a series of fixed heights.

Tables

Table I.

The shape transition process between symmetric and asymmetric structures for different growth and surface energy conditions. The truncated-hut structures shown here are only suitable for limited height with a minimum strain energy at a certain aspect ratio not equal to 1.
