Patent number: 9213241Abstract: A method for making nanostructure is provided. The method includes following steps. A conductive layer including a graphene film is applied on an insulating substrate. A resist layer is placed on the conductive layer. A number of openings are formed by patterning the resist layer via electron beam lithography. A part of the conductive layer is exposed to form a first exposed portion through the plurality of openings. The first exposed portion of the conductive layer is removed to expose a part of the insulting substrate to form a second exposed portion. A preform layer is introduced on the second exposed portion of the insulating substrate. Remaining resist layer and remaining conductive layer are eliminated. A number of nanostructures are formed.Type: GrantFiled: April 2, 2014Date of Patent: December 15, 2015Assignees: Tsinghua University, HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Jun-Ku Liu, Meng-Xin Ren, Li-Hui Zhang, Mo Chen, Qun-Qing Li, Shou-Shan Fan

Patent number: 8628237Abstract: A method for measuring a contacting thermal resistance of one-dimensional structures is provided. A first one-dimensional structure and A second one-dimensional structure are crossed and in contact with each other to form a suspended junction. A point P of the first one-dimensional structure is heated until the first one-dimensional structure and the second one-dimensional structure reach a thermal equilibrium. A point A and a point B are selected on the first one-dimensional structure and a point C and a point D are selected on the second one-dimensional structure, wherein the point B, the point A, the suspended junction, the point C and the point D are arranged equidistantly with a distance ?x. A temperature difference ?Tj is calculated by the formula ?Tj=?TAC??TBA??TCD. The heat flux Qj is calculated by the formula Qj=2k?TCD/?x. The contacting thermal resistance Rj is calculated by the formula Rj=?Tj/Qj.Type: GrantFiled: January 24, 2013Date of Patent: January 14, 2014Assignees: Tsinghua University, Hon Hai Precision Industry Co., Ltd.Inventors: Jun-Ku Liu, Qun-qing Li, Yuan Zou, Shou-Shan Fan
