Abstract:
An inverse photoemission spectroscopy apparatus is configured to detect a light generated by the relaxation of electrons to an unoccupied state of a sample. The apparatus includes an electron source for generating electrons with which a sample is irradiated, a wavelength selector for extracting a light having a certain wavelength from the light generated in the sample, a photodetector for detecting the light extracted by the wavelength selector; and a focusing optics disposed between the sample and the photodetector. The electron source contains yttrium oxide as a thermionic emission material.

Abstract:
Provided is a technique for fabricating a novel thin membrane with a starting material such as a biocompatible compound that is not easily processible into a membrane, particularly a technique for fabricating a novel thin membrane of a composition that is gradually polymerized from a membrane surface into the membrane in the cross sectional direction of the membrane, and having, for example, different structures on the front and back of the membrane. The technique includes the steps of preparing a solution of a starting material compound; forming a thin membrane of the solution on a base material surface; and forming the organic polymer thin membrane through a polymerization reaction caused by irradiating the exposed surface of the thin membrane with a plasma or an electron beam.

The object of the present invention is to provide a polymer brush which forms phase-separated structure in a gas phase. The polymer brush according to the present invention comprises a substrate and a polymer layer wherein the polymer layer comprises polymer chains each of which has one end fixed on the substrate and other end free-ended, and wherein a state of phase-separation between a polymer dense part and a polymer thin part reversibly changes in the polymer layer.
Abstract:
A tunnel field-effect transistor (TFET) is configured by disposing a III-V compound semiconductor nano wire on a (111) plane of a IV semiconductor substrate exhibiting p-type conductivity, and arbitrarily disposing electrodes of a source, drain and gate. Alternatively, the tunnel field-effect transistor is configured by disposing a III-V compound semiconductor nano wire on a (111) plane of a IV semiconductor substrate exhibiting n-type conductivity, and arbitrarily disposing electrodes of a source, drain and gate. The nano wire is configured from a first region and a second region. For instance, the first region is intermittently doped with a p-type dopant, and the second region is doped with an n-type dopant.

A transistor includes: a piezoresistor through which carriers conduct; a source that injects the carriers into the piezoresistor; a drain that receives the carriers from the piezoresistor; a piezoelectric material that is located so as to surround the piezoresistor and applies a pressure to the piezoresistor; and a gate that applies a voltage to the piezoelectric material so that the piezoelectric material applies a pressure to the piezoresistor.
Abstract:
A structure used for animal cells is provided which includes an elastic body layer having a flat surface on which animal cells are left. The elastic body layer has a surface whose elasticity is changed by partially supporting the elastic body layer from the rear side or by changing a thickness of the elastic body layer.
Abstract:
A process for producing a Co-base alloy which has a basic composition including, in terms of mass proportion, 0.1%-10% Al, 3.0-45% W, and Co as the remainder and has an intermetallic compound of the L12 type [Co3 (Al,W)] dispersed and precipitated therein. Part of the Co may be replaced with Ni, Ir, Fe, Cr, Re, or Ru, while part of the Al and W may be replaced with Ni, Ti, Nb, Zr, V, Ta or Hf. The intermetallic compound [Co3 (Al, W)] has a high melting point, and this compound and the matrix are mismatched little with respect to lattice constant. Thus, the cobalt-base alloy can have high-temperature strength equal to that of nickel-base alloys and excellent structure stability.
