摘要:
Provided is a ZnO-based semiconductor device capable of growing a flat ZnO-based semiconductor layer on an MgZnO substrate having a main surface on the lamination side oriented in a c-axis direction. ZnO-based semiconductor layers 2 to 6 are epitaxially grown on an MgxZn1-xO (0≦x≦1) substrate 1 having a +C surface (0001), as a main surface, inclined at least in an m-axis direction. A p-electrode 8 is formed on the ZnO-based semiconductor layer 5, and an n-electrode 9 is formed on the underside of the MgxZn1-xO substrate 1. Thereby, steps regularly arranged in the m-axis direction can be formed on the surface of the MgxZn1-xO substrate 1, and a phenomenon called step bunching is prevented. Consequently, the flatness of a film of the semiconductor layers laminated on the substrate 1 can be improved.

A magnet for a dynamo-electric machine has a plurality of magnetic poles disposed substantially in a circular shape and opposite a plurality of teeth disposed substantially in a circular shape, the magnetic poles and teeth separated by a gap in an axial direction of a revolving shaft. A plurality of inter-pole sections extend circumferentially between adjacent magnetic poles out of the plurality of magnetic poles. The inter-pole sections have tooth-opposed surfaces that are recessed relative to the surfaces of the magnetic poles opposite the teeth in the direction of the revolving shaft. The plurality of magnetic poles and the plurality of inter-pole sections are integrally formed.
摘要:
The present invention provides a magnetic sensor capable of reproducing a magnetic record even if the size of a recorded magnetization is a minute one, directly reading a magnetization recorded on a magneto-optical disk without applying incident light itself to the magneto-optical disk, and obtaining signals of a second harmonic having a high S/N ratio. This magnetic sensor includes a magnetic sensor element (102) having electric polarization disposed with respect to a perpendicular recording medium (101), and laser generating means acting on the magnetic sensor element (102). The magnetic sensor reads information in the perpendicular recording medium (101) based on the variation of the rotation angle φ of the polarization plane of a second harmonic (105) of a frequency 2ω exiting the magnetic sensor element (102) by the application of laser light (104) with a frequency ω from the laser generation means to the magnetic sensor element (102).

A transistor is provided, which is entirely and partially transparent by the use of a transparent channel layer made of zinc oxide or the like. A channel layer 11 formed of a transparent semiconductor such as zinc oxide ZnO. A transparent electrode is used for all of a source 12, a drain 13 and a gate 14, or a part of them. As the transparent electrode, a transparent conductive material such as conductive ZnO doped with, for example, group III elements is used. As a gate insulating layer 15, a transparent insulative material such as insulative ZnO doped with elements capable of taking a valence of one as a valence number or group V elements is used. If a substrate 16 must be transparent, for example, glass, sapphire, plastic or the like can be used as a transparent material.

摘要:
In a thin film transistor (1), a gate insulating layer (4) is formed on a gate electrode (3) formed on an insulating substrate (2). Formed on the gate insulating layer (4) is a semiconductor layer (5). Formed on the semiconductor layer (5) are a source electrode (6) and a drain electrode (7). A protective layer (8) covers them, so that the semiconductor layer (5) is blocked from an atmosphere. The semiconductor layer (5) (active layer) is made of, e.g., a semiconductor containing polycrystalline ZnO to which, e.g., a group V element is added. This allows practical use of a semiconductor device which has an active layer made of zinc oxide and which includes an protective layer for blocking the active layer from an atmosphere.
