摘要： The present invention relates to a method for manufacturing a diamond substrate, and more particularly, to a method of growing diamond after forming a structure of an air gap having a crystal correlation with a lower substrate by heat treatment of a photoresist pattern and an air gap forming film material on a substrate such as sapphire (Al2O3). Through such a method, a process is simplified and the cost is lowered when large-area/large-diameter single crystal diamond is heterogeneously grown, stress due to differences in a lattice constant and a coefficient of thermal expansion between the heterogeneous substrate and diamond is relieved, and an occurrence of defects or cracks is reduced even when a temperature drops, such that a high-quality single crystal diamond substrate may be manufactured and the diamond substrate may be easily self-separated from the heterogeneous substrate.

摘要： A method for measuring critical current density of superconductor wires according to the present invention is characterized in that it includes: (a) applying an external magnetic field to the superconductor wires, (b) measuring a magnetization loss of the superconductor wires according to the application of the external magnetic field, (c) normalizing the measured magnetization loss, and then calculating a fully-penetration magnetic field of the superconductor wires according to the normalized magnetization loss, (d) calculating a critical current density of the superconductor wires according to the calculated fully-penetration magnetic field. Therefore, the critical current density of parallel superconductor wires such as stacked superconductor wires may be measured without applying current to the superconductor wires directly.

摘要： A linear motor and a camera module having the linear motor are provided. The linear motor includes: a piezoelectric substrate generating a vibration mode in a longitudinal direction on the basis of an applied voltage; first and second shafts coupled to both sides of the piezoelectric substrate with the piezoelectric substrate interposed therebetween; and a moving member coupled to at least one of the first and second shafts to be movable in the longitudinal direction of the first and second shafts and connected to a camera lens on one side. Accordingly, it is possible to remove a dead zone with a simple structure, to prevent an unnecessary increase in thickness, not to cause a stoppage at the time of moving a camera lens, to cause a small amount of tilt to enable a linear control, and to contribute to a decrease in thickness and a compactness of a mobile terminal.
