Query: Deterministic aperiodic composite lattice-structured silicon thin films
  for photon management   Exotic manipulation of the flow of photons in nanoengineered semiconductor
materials with an aperiodic distribution of nanostructures plays a key role in
efficiency-enhanced and industrially viable broadband photonic technologies.
Through a generic deterministic nanotechnological route, in addition to
periodic, transversely quasicrystallographic or disordered random photonic
lattices, here we show scalable nanostructured semiconductor thin films on
large area nanoimprinted substrates up to 4cm^2 with advanced functional
features of aperiodic composite nanophotonic lattices having tailorable
supercell tiles. The richer Fourier spectra of the presented artificially
nanostructured materials with well-defined lattice point morphologies are
designed functionally akin to two-dimensional incommensurate intergrowth
aperiodic lattices-comprising periodic photonic crystals and in-plane
quasicrystals as subgroups. The composite photonic lattice-structured
crystalline silicon thin films with tapered nanoholes or nanocone-nanoholes are
presented showing up to +30 % achievable short circuit current density in
comparison to a periodic counterpart where as it is up to +190 % in comparison
to a reference unstructured silicon thin film of 300 nanometers of thickness.
In view of scalable bottom-up integrated device fabrication processes, the
structural analysis is further extended to liquid phase crystallized
double-side-textured deterministic aperiodic lattice-structured 10 micrometers
thick large area crystalline silicon film.
