Abstract

To provide a volume-type optical element in which a self-cloning photonic crystal is used. An optical element is provided with half-wave plates of photonic crystals formed on the xy plane and laminated in the z-axis direction in a three-dimensional space x, y, z. The groove direction of the photonic crystals is a curved line, and the angle in relation to the y-axis direction changes continuously in the range of 0°-180°. Light entering the optical element in the axial direction is emitted from the optical element upon being divided and converted into clockwise circularly polarized light in the direction facing the x-axis by a given angle from the z-axis and anticlockwise circularly polarized light in the direction facing the −x-axis by a given angle from the z-axis. Laminating or placing a quarter-wave plate comprising a photonic crystal on one or both surfaces makes it possible to divide light entering from the z-axis direction of the optical element into two orthogonal linearly polarized lights.

The groove direction of the photonic crystals is a curved line, and the angle in relation to the y-axis direction changes continuously in the range of 0°-180°. Light entering the optical element in the axial direction is emitted from the optical element upon being divided and converted into clockwise circularly polarized light in the direction facing the x-axis by a given angle from the z-axis and anticlockwise circularly polarized light in the direction facing the –x-axis by a given angle from the z-axis. Laminating or placing a quarter-wave plate comprising a photonic crystal on one or both surfaces makes it possible to divide light entering from the z-axis direction of the optical element into two orthogonal linearly polarized lights.

Abstract

According to the present invention, electrode layers 24, 26 are connected to a bismuth ferrite layer 22 by being arranged so as to sandwich the bismuth ferrite layer 22 from a direction that is perpendicular to the c-axis of a bismuth ferrite crystal that constitutes the bismuth ferrite layer 22. An electric field in a direction that is perpendicular to the c-axis of the bismuth ferrite crystal is applied to the bismuth ferrite layer 22 by applying a voltage between the electrode layers 24, 26. Consequently, the present invention is able to provide a nonvolatile memory having low power consumption, to which data is able to be written.

Abstract

A plant cultivation method that comprises promoting the growth of a plant by microwave radiation. In a preset timing after a seed or bulb under cultivation germinates and shoots, the shoot or seedling is radiated with microwave for a preset period of time. In the microwave radiation to the germinating shoot or seedling, it is preferred to appropriately control the output and radiation time of the microwave so as to avoid heating of the radiation target by the microwave. For example, the output of the microwave is controlled to preferably 50 W or less, more preferably 30 W or less, and the radiation time thereof is controlled to preferably 120 minutes or shorter, more preferably 90 minutes or shorter. According to this treatment, the switch timing from the vegetative growth stage to the reproductive growth stage can be put forward and the growth condition of the plant in the vegetative growth stage can be improved in an environment that is disadvantageous for plant growth.

Abstract

A repellant for repelling root-knot nematodes (Meloidogyne spp.) that comprises as an active ingredient a substance secreted by a cellular slime mold belonging to the genus Dictyostelium. The substance secreted by the cellular slime mold can be obtained by, for example, culturing the cellular slime mold to form fruiting bodies, then separating the cellular slime mold and extracting. As the cellular slime mold, D. discoideum, D. purpureum, D. mucoroides, D. fasciculatum, D. monochasioides, D. lacteum or D. giganteum may be used. Thus, root-knot nematodes can be repelled without exerting any bad influence upon crops and workers.

Abstract

Hydrogen can be efficiently generated with a small amount of electrolysis energy. Generate hydrogen by electrolysing liquid ammonia having electrolytes added thereto, and generate electricity by reacting the generated hydrogen with oxygen. As the electrolysis energy for the liquid ammonia is low, a large amount of hydrogen can be efficiently generated. The electrical energy obtained from the hydrogen generated by electrolysis is greater than the electrical energy needed for the electrolysis of the liquid ammonia. Therefore, a small electricity source can be converted to a large electrical power and used.

Abstract

A III nitride structure is provided with a substrate (102), and a fine wall-like structure (110), which is arranged upright on the substrate (102) in the direction vertical to a surface of the substrate (102) and extends in the in-plane direction of the substrate (102). The fine-wall-like structure (110) contains a III nitride semiconductor crystal, and when the height of the fine-wall-like structure (110) is expressed as (h), and the width of the fine-wall-like structure in the direction orthogonally intersecting with the height direction and the extending direction is expressed as (d), (h) is larger than (d).

Abstract

A III nitride structure includes a film (108) having a surface composed of a metal formed in a prescribed region on the surface of a substrate (102); and a fine columnar crystal (110) composed of at least a III nitride semiconductor formed on the surface of the substrate (102). The spatial occupancy ratio of the fine columnar crystal (110) is higher on the surface of the substrate (102) where the film (108) is not formed than that on the film (108).

Abstract

A method of manufacturing a semiconductor element by forming, on a substrate, columnar crystals of a nitride-base or an oxide-base compound semiconductor, and by using the columnar crystals, wherein on the surface of the substrate, the columnar crystals are grown while ensuring anisotropy in the direction of c-axis, by controlling ratio of supply of Group-III atoms and nitrogen, or Group-II atoms and oxygen atoms, and temperature of crystal growth, so as to suppress crystal growth in the lateral direction on the surface of the substrate.
