Abstract:
PROBLEM TO BE SOLVED: To provide a power generation system capable of obtaining both electric energy and heat energy with the use of light energy.SOLUTION: A power generation system 1 comprises: a gas generation part 10 which includes an electrolyte A and a plurality of semiconductor chips 12 having a photoelectric conversion function contained in a container 11, and which absorbs light energy to generate gas; a power generation part 20 which uses the gas generated by the gas generation part 10 to produce electric energy; and a water heater 30 which absorbs heat energy from the inside of the container 11. In the gas generation part 10, light incident into the container 11 is absorbed by the plurality of semiconductor chips 12 to cause electrolysis in the electrolyte A. Gas (such as hydrogen) is generated in the container 11, and the power generation part 20 produces electric energy by using the generated gas. Temperature inside the container 11 rises due to reaction heat by the electrolysis and radiation heat from sunlight, and the heat energy inside the container 11 is absorbed by the water heater 30.

PROBLEM TO BE SOLVED: To provide a pore structure showing excellent adhesion with a substrate electro-conductive layer and having a surface with improved flatness, to provide its production method, to provide a memory device using the pore structure, to provide its production method, to provide an adsorption amount analyzer, and to provide a magnetic recording medium. SOLUTION: A base electro-conductive layer 2 and an Al-Hf alloy layer 3 (or a stacked body of the Al-Hf alloy layer 3 and an Al layer) are formed on a substrate 1 in a stacked state. A simple substance composed of Pt, Ir, Pd, Rh, Au, Ag, Ru, Cu or Ni or an alloy thereof having satisfactory adhesion to the Al-Hf alloy layer 3 is used for the base electro-conductive layer 2. Next, the Al-Hf alloy layer 3 (or the stacked body) is anodized in an acid aqueous solution to form a nanohole structure having nanoholes 8, and, if required, the nanoholes 8 are subjected to width expansion working by etching. Then, a functional material 10 such as a ferroelectric material, a ferromagnetic material, a variable resistance material, a phase transition material and a phosphor material is filled into the nanoholes, by which the nanohole structure having various functions is produced.

Abstract:
PROBLEM TO BE SOLVED: To realize an epitaxial rare earth oxide (110)/silicon (001) structure by well epitaxially growing a rare earth oxide such as cerium oxide of the (110) face orientation on a silicon substrate of the (001) face orientation at a lower growth temperature than that of a conventional method. SOLUTION: The surface of an Si substrate 1 of the (001) face orientation is converted into a dimer structure by surface reconstruction of 2×1 and 1×2 and a raw material comprising at least one or more kinds of rare earth elements is used in an atmosphere containing an oxidizing gas to epitaxially grow a cubic or a tetragonal rare earth oxide, e.g. a CeO2 membrane 2 of the (110) face orientation. At the time of the growth, the feed of the oxidizing gas to the surface of the Si substrate 1 is started and the feed of the raw material comprising at least the one or more kinds of the rate earth elements is then carried out.
