    摘要: Die Erfindung beschreibt ein Verfahren zur Herstellung von relaxierten Epitaxieschichten auf einem Halbleitersubstrat mittels Molekularstrahlepitaxie mit einer Wasserstoffquelle, indem in einer in situ Prozeßfolge

    an oder nahe der Substratoberfläche eine wasserstoffhaltige Zwischenschicht deponiert oder eingebracht wird,
    darauf eine verspannte Epitaxieschicht aufgewachsen wird und
    die Epitaxieschicht mittels einer Temperaturbehandlung relaxiert wird.

    摘要: An ultrafine Al particle consists of an Al multiply twinned particle. The Al multiply twinned particle has a decahedron structure surrounded by {111} planes. The Al multiply twinned decahedral partucle has a diameter of 10 to 30 nm. Such an ultrafine Al particle consisting of the Al multiply twinned decahedral particle is obtained as follows. A metastable Al oxide particle is placed on an amorphous carbon substrate having the reduction effect. Then the electron beam is irradiated to the metastable Al oxide particle placed on the amorphous carbon substrate in the vacuum atmosphere. From the metastable Al oxide particle, Al atoms or Al clusters are emitted and adsorbed to the substrate. By adjusting the electron beam intensity so that the ultrafine Al particle in the above procedure has a diameter from 10 to 30 nm, the Al multiply twinned particle having a decahedron is obtained.

    摘要: The present invention has been achieved by perceiving the fact to the effect that a semiconductor production process-like manner such as CVD method or the like by which materials and film thickness can be controlled in an atomic scale may be utilized in case of preparing thin-film crystal, and employing such semiconductor production process-like manner being quite different from conventional technique. The invention relates to preparation of crystalline thin-films for solid-state lasers wherein a substrate contained in a vessel under a high vacuum condition is heated, materials for forming the laser material are supplied onto the surface of the aforesaid substrate in the form of gas, ion, single metal or metal compound to grow crystal on the surface of the aforesaid substrate, and a material of active ionic species is supplied onto the surface of the aforesaid substrate simultaneously with supply of the aforesaid materials for forming the laser host crystal, thereby controlling valence number of the material of active ionic species so as to be identical with the valence number of the metal ion constituting the crystal of the aforesaid laser host crystal.
