Abstract:
1. An electrical structure comprising: at least a first and second electrode; a monocrystalline silicon-containing material having a surface substantially free of oxidation, H-terminated and a porosity of not more than 30%; and an organic layer chemically bonded to the surface of the silicon-containing material, the organic layer having more than half of its atoms being carbon and hydrogen and formed in the presence of an alcohol-ferrocene solution, the organic layer immediately adjacent to the region of monocrystalline silicon-containing material and wherein the first electrode is formed on the organic layer, wherein an electrical property of the electrical structure selected from surface recombination velocity, carrier lifetime, electronic efficiency, voltage device capacitance, contact resistance, and resistance of a doped region of the electrical structure is changed compared to the electrical property of the electrical structure in the absence of the organic layer, and wherein as a result of said organic layer being chemically bonded to the surface of the silicon-containing material, said surface comprises a measurable carrier lifetime for low-level injection of more than approximately 7.8 μs or for high-level injection of more than approximately 12 μs, or a measurable surface recombination velocity of less than approximately 1300 cm/s for low level injection or 810 cm/s for high level injection.
