DEVICE:
- self-assembled quantum dots
PROBLEM:
- Atomistic strain is too expensive to compute.
- Analytical strain is inaccurate and exist only for cuboid shape.
OBJECTIVE:
- Significantly reduce computations.
RESULTS/IMPACT:
- Atomistic strain depends on aspect ratio and materials and not on individual dimensions.
- Fitted compact expressions that provide atomistic strain.
- Compact model (EM) that sacrifices 5% accuracy but cost 20K less computations.
