Aims and Scope

The origin of New Physics: Sae Mulli (NPSM, ISO abbreviation: New Phys.: Sae Mulli.): Sae Mulli (새물리 in Korean characters means ‘new physics’) is the oldest Korean pure scientific journal. It was first published in 1961 just after the Korean War by the Korean Physical Society (KPS). The primary mission of Sae Mulli was to start building up Korean physics research community from almost nothing and in fact Sae Mulli had made tremendous contributions to the Korean science community. Through a peer-review system, Sae Mulli had continued elevating the level of scientific researches, consequently becoming a cornerstone of the economic miracle of Korea...

Development of Low-Cost ESPI for a School Environment
Jeongwoo PARK, Junehee YOO*
Department of Physics Education, Seoul National University, Seoul 08826, Korea
The purpose of this study is to develop a low-cost electronic speckle pattern interferometer (ESPI) for a school environment. This ESPI can be built for a small fraction of the cost of a commercial version. This interferometer is constructed with a few optical components and a web cam. The vibration modes of a circular plate can be visualized in real time by using a desktop computer and a LabView program written by the author. A material that connects the hologram image of each mode and the FFT graph can be used as an example of connecting abstract and concrete representations in school. If the ESPI is to be used in a school environment, the education content must be deveploped. In addition, a high-resolution camera is needed, the LabView program must be improved and the experimental conditions must be optimized.

AlN has many advantages for ultraviolet (UV) light-emitting diodes (LEDs). But an AlN epilayer has not been successfully grown on a PSS (patterned sapphire substrate). In this research, AlN epilayers were grown on cone-shape c-plane PSS by using a mixed-source HVPE (hydride vapor-phase epitaxy). The surface morphologies and the crystal structures of the AlN epilayers grown by using a mixed source with metallic Al and Ga sources were investigated by SEM (scanning electron microscopy) and XRD (X-ray diffraction). SEM images showed that the flat c-plane of an AlN epilayer was grown on a PSS around a cone and that the growth rate of the AlN epilayer increased when the Ga/Al ratio of the mixed source was increased. The XRD results showed that c-plane AlN was grown dominantly by using mixed sources with low Ga/Al ratios below 0.1, GaN epilayers were dominantly grown by using mixed sources with high Ga/Al ratios above 0.4. On the other hand, the growth rate for a high Ga/Al ratio was higher than that for a low Ga/Al ratio. Therefore, to optimized Ga/Al ratios of 0.05 $\sim$ 0.2, one can expect to grow in a short growth time a single-crystal flat AlN epilayer on a PSS.
