Abstract: A semiconductor laminate film includes a silicon substrate and a semiconductor layer formed on the silicon substrate and containing silicon and germanium. The semiconductor layer having a surface roughness Rms of 1 nm or less. Further, the semiconductor layer satisfies the following relationship t?0.881×x?4.79 where t represents a thickness (nm) of the semiconductor layer, and x represents a ratio of the number of germanium atoms to a sum of the number of silicon atoms and the number of germanium atoms in the semiconductor layer. Also, the semiconductor layer being a mixed crystal semiconductor layer containing silicon and germanium.

Abstract: A method for efficiently producing a high-purity metal hydride without contamination of other metals while initiating reaction rapidly is provided. A method for producing a metal hydride from a metal selected from the group consisting of Group 2 metals and Group 3 metals comprising: (A) charging the pressure resistant container with the metal, introducing hydrogen into the container, and heating the container to initiate reaction, wherein a gauge pressure (a) is set to 0.1 to 1.5 MPa, a heating temperature (b) is set to 50 to 250° C., and a product of the gauge pressure and the heating temperature, a×b, is set in the range of 20 to 100; (B) stopping the introduction of hydrogen to allow the reaction to proceed when the temperature in the reaction container is increased to a temperature higher by 10 to 100° C. than the heating temperature; (C) introducing hydrogen of 0.1 to 1.

Abstract: A shell is constructed by an outer shell and an end plate. The end plate has a port into a liquid champer and a gas champer. A bladder divides an internal space of the shell into a liquid champer and a gas champer. A gas is introduced into the gas chamber without the provision of a gas inlet hole in the outer shell located on the side of the gas champer. For example, an accumulator is assembled by combining the outer shell, the end plate and bladder under atmosphere of a high pressure gas.
