Fig. 4.
Spatial distribution of electrostatic and elastic energies (in units of kBT, where T is the room temperature) on the surface of the disc (upper two rows) and bowl (lower two rows). The left column shows the front view, the center column shows the angle view, and the right column shows the side view. For either shapes, the elastic energy (second and fourth rows) is concentrated in the edges. The electrostatic energy on the disc (first row) is higher in the center where the opposite faces are nearby. The five-coordinated vertices, which are visible as spots in the electrostatic energy distribution, lead to small fluctuations in the energy.
