    摘要: A photonic quantum ring (PQR) laser includes an active layer having a multi-quantum-well (MQW) structure and etched lateral face. The active layer is formed to be sandwiched between p-GaN and n-GaN layers epitaxially grown on a reflector disposed over a support substrate. A coating layer is formed over an outside of the lateral faces of the active layer, and upper electrode is electrically connected to an upper portion of the n-GaN layer, and a distributed Bragg reflector (DBR) is formed over the n-GaN layer and the upper electrode. Accordingly, the PQR laser is capable of oscillating a power-saving vertically dominant 3D multi-mode laser suitable for a low power display device, prevent the light speckle phenomenon, and generate focus-adjusted 3D soft light.

    摘要: There is provided a thin film capacitor and a capacitor-embedded printed board improved in leakage current characteristics. A dielectric layer is formed of a BiZnNb-based amorphous metal oxide with a predetermined dielectric constant without being heat treated at a high temperature, and metallic phase bismuth of the BiZnNb-based amorphous metal oxide is adjusted in content to attain a desired dielectric constant. Also, another dielectric layer having a different content of metallic phase bismuth may be formed. The thin film capacitor including: a first electrode; a dielectric layer including a first dielectric film formed on the first electrode, the dielectric layer comprising a BiZnNb-based amorphous metal oxide; and a second electrode formed on the dielectric layer, wherein the BiZnNb-based amorphous metal oxide contains metallic phase bismuth.
