| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Current path control in nitride semiconductor-based devices with tunnel junctions have been investigated along the following two aspects. First, LEDs with tunnel junctions and top n-GaN layers for current spreading were fabricated. Light extraction was improved 1.4 times compared to that of standard LEDs with semi-transparent electrodes. This indicates that the currents were sufficiently spreading at the top n-GaN layers and no light was absorbed at the electrodes. Next, current density distribution and device resistance were estimated in nitride-based vertical cavity surface emitting lasers with the tunnel junctions by finite element method. A reasonably low resistance, 200Ω, was obtained in a suitable device structure, implying potential cw operations at room temperature. | |
