### Piezo charges in a spherical Quantum dot

We calculated a theoretical $In_{0.2}Ga_{0.8}As$ spehrical quantum dot in a $GaAs$ matrix. The radius of the sphere was $2nm$, which creates the following piezo charge distribution around itself in Figure 1.

In Figure 2. we plotted the piezo charges over a line, which is drawn over the diagonal of the system.
