Patent number: 9029174Abstract: A structure includes a substrate, a template layer formed on the surface of the substrate and including an AlN layer, and a device structure portion formed by stacking AlGaN semiconductor layers on the template layer. For the structure, the AlN layer is irradiated from a side close to the substrate with a laser light with a wavelength by which the laser light passes through the substrate and the laser light is absorbed by the AlN layer, in a state in which the AlN layer receives compressive stress from the substrate. This allows the AlN layer to expand more than the surface of the substrate on at least an interface between the AlN layer and the substrate so as to increase the compressive stress, in order to remove the substrate from the AlN layer.Type: GrantFiled: February 25, 2011Date of Patent: May 12, 2015Assignees: Meijo University, Soko Kagaku Co., Ltd.Inventors: Motoaki Iwaya, Hiroshi Amano, Isamu Akasaki

Patent number: 8709539Abstract: A process and an apparatus for producing a composite material utilize a rotatable hollow body that is inclined with an upstream side being higher than a downstream side. A reaction zone is defined within an elongated chamber in the hollow body. Protrusions inwardly extend from an inner peripheral wall of the hollow body adjacent to the reaction zone. Base material is input into the chamber via a base material introduction port and a carbon source vapor is input into the chamber via a carbon source supply port. A heater heats the reaction zone to a temperature at which carbon nanotubes form on the base material from the carbon source vapor. The protrusions catch base material disposed on the inner peripheral wall of the hollow body when the hollow body rotates and then drop the base material through the reaction zone so that the base material contacts the carbon source vapor.Type: GrantFiled: February 2, 2010Date of Patent: April 29, 2014Assignees: Meijo University, Meijo Nano Carbon Co., Ltd., Masuoka Ceramic Materials Co., Ltd.Inventors: Yoshinori Ando, Mukul Kumar, Takeshi Hashimoto, Norio Kurauchi, Hirotaka Masuoka, Akira Kagohashi
