Abstract
An inorganic two-phase nanowire structure including an inorganic semiconducting nanoporous charge conducting phase, and, an inorganic semiconductor nanowire array disposed within at least one of the pores of the nanoporous charge conducting phase.
Claims20
An inorganic two-phase nanowire structure with at least one ordered phase comprising:
- an inorganic semiconducting nanoporous charge conducting phase;
- and,
- an inorganic semiconductor nanowire array interpenetrated within the nanoporous charge conducting phase.
A method for producing an inorganic two-phase nanowire structure, comprising:
- providing a nanoporous phase and an inorganic precursor material for the formation of nanowires;
- and,
- electrochemically producing an inorganic two-phase nanowire structure by controlling the effective electron diffusion length.
A method for production of a nanowire structure comprising:
- forming a nanowire array without a corresponding conducting phase, and,
- filling the spaces in the nanowire array with a corresponding conducting phase;
- wherein the these operations may be performed either in this order or in reverse order.
