    摘要: A pumped sensor system includes a substrate with a first layer formed thereon and doped for a first type conduction and a second layer doped for a second type conduction, whereby the first and second layers form a silicon light detector at an up-conversion wavelength. A ternary rare earth oxide is formed on the second layer and crystal lattice matched to the second layer. The oxide is a crystalline bulk oxide with a controlled percentage of an up-conversion component and a majority component. The majority component is insensitive to any of pump, sense, or up-conversion wavelengths and the up-conversion component is selected to produce energy at the up-conversion wavelength in response to receiving energy at the pump and sense wavelengths. The layer of oxide defines a light input area sensitive to a pump wavelength and a light input area sensitive to a sense wavelength.

    摘要: A method of forming a template on a silicon substrate includes epitaxially growing a template of single crystal ternary rare earth oxide on a silicon substrate and epitaxially growing a single crystal semiconductor active layer on the template. The active layer has either a cubic or a hexagonal crystal structure. During the epitaxial growth of the template, a partial pressure of oxygen is selected and a ratio of metals included in the ternary rare earth oxide is selected to match crystal spacing and structure of the template at a lower interface to the substrate and to match crystal spacing and structure of the template at an upper interface to crystal spacing and structure of the semiconductor active layer. A high oxygen partial pressure during growth of the template produces a stabilized cubic crystal structure and a low oxygen partial pressure produces a predominant peak with a hexagonal crystal structure.

    摘要: A method of forming a layer of amorphous silicon oxide positioned between a layer of rare earth oxide and a silicon substrate. The method includes providing a crystalline silicon substrate and depositing a layer of rare earth metal on the silicon substrate in an oxygen deficient ambient at a temperature above approximately 500° C. The rare earth metal forms a layer of rare earth silicide on the substrate. A first layer of rare earth oxide is deposited on the layer of rare earth silicide with a structure and lattice constant substantially similar to the substrate. The structure is annealed in an oxygen ambience to transform the layer of rare earth silicide to a layer of amorphous silicon and an intermediate layer of rare earth oxide between the substrate and the first layer of rare earth oxide.
