Atomistic Hamiltonian

Crystalline Structure

Atomic-like Orbitals

We employ an empirical s,p,d, s* tight-binding Hamiltonian to simulate Quantum Dots. The wavefunction is represented as a linear combination of orthogonal atomic-like orbitals. Full crystal and wavefunction symmetry is accounted for in this model. Since only nearest neigbor, two-center integral terms are included in the Hamiltonian, strain is included in a straightforward and intuitive manner.
