Accurate atomic-scale quantum theory of
nanostructures and nanosystems fabricated
from nanostructures enables precision
metrology of these nanosystems and
provides the predictive, precision modeling
tools needed for engineering these systems
for applications including advanced
semiconductor lasers and detectors, single
photon sources and detectors, biosensors,
and nanoarchitectures for quantum
coherent technologies such as quantum
computing. The tight-binding model based
upon the Linear Combination of Atomic
Orbitals (LCAO) method provides an
accurate atomistic theory for
nanostructures.
