| Abstract(in English) | Self-organized GaN nanocolumns are one-dimensional columnar nano-crystals, which have about 100nm in diameter and 1μm in height. Nanocolumns have high optical properties due to almost dislocation-free nature. And also, strong localization of light is expected in nanocolumns due to it's randomly distribution. In this study, we observed the random laser action in self-organized GaN nanocolumns for the first time. Polarization behavior, sample dependence, and theoretical approach using 2D-FDTD method will be also presented. |
