  • Patent number: 5900391
    Abstract: Herein disclosed is a method for depositing a high Tc superconducting thin film. The superconducting thin film is deposited on one surface of a substrate. The substrate is exposed to an electromagnetic wave to heat the substrate during the process for depositing the superconducting thin film. Before the processes for depositing the superconducting thin film and exposing the substrate to the electromagnetic wave, a dummy film is formed on the other surface of the substrate. The dummy film has absorbency of the electromagnetic wave which is higher than that of the substrate. The dummy film together with the substrate is exposed to the electromagnetic wave while the superconducting thin film is deposited on the one surface of the substrate. The superconducting thin film thus deposited has superconductivity and high quality crystal structure.

  • Patent number: 5449928
    Abstract: A pseudomorphic HEMT of a structure which prevents the distribution of 2DEG in the channel layer from being concentrated near the hetero-interface relative to a doping layer and which, at the same time, enables the thickness of the channel layer to which distortion is imparted to be decreased. In an n-InAlAs/InGaAs pseudomorphic structure grown on an InP substrate 1, an InGaAs spacer layer 4 having an In composition ratio smaller than that of an InGaAs channel layer 3 is inserted in an InAlAs/InGaAs hetero-interface. The InGaAs channel layer 3 has an In composition ratio of 0.80 to exhibit a high mobility. Another InAlAs buffer layer 2, spacer layer 5 and doping layer 6 have an In composition ratio of 0.52 which is in lattice-match with the substrate, and InGaAs spacer layer 4 and cap layer 7 have an In composition ratio of 0.53 which is in lattice-match with the substrate. This constitution makes it possible to control the two-dimensional electron gas and to further increase the mobility.

The second semiconductor layer is formed on the first semiconductor layer and has a different lattice constant from the first semiconductor layer to thereby apply a second strain to the second semiconductor layer. The second strain has a direction that is inverse to the first strain direction. In addition, the thickness of the semiconductor layer is defined so as to compensate for the first strain applied to the first semiconductor layer by the second strain applied to the second semiconductor.

  • Patent number: 4673248
    Abstract: A reflecting mirror for use as a rearview mirror in an automobile, the mirror having a plurality of thin layers arranged on a glass plate. One of the layers is made of a transparent dielectric material having a refractive index which is not less than a refractive index of WO.sub.2 and the other is made of a metal material having a reflecting factor ranging between 50-70%. The light introduced into the mirror is reflected at different borders formed in the mirror between the layers so as to provide lights of different phases. Therefore, there is an interference, and, consequently, the mirror provides a certain selected tone in accordance with the value of the optical thickness of the transparent dielectric layer, resulting in an anti-glare effect and a deep color.
