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...

Three-dimensional (3D) histology is an imaging system for acquiring 3D structural information on cells or tissues. Understanding the 3D structure of tissues and cells by using 2D sections is difficult. A general 3D reconstruction method by stacking serial sectioned images of a tissue is hard work and can lead to reconstruction errors through sections that are torn or missing. Experiments were performed at the beamline 6C of the Pohang Light Source (PLS) using phase-contrast X-ray imaging method, a computer-controlled precision stage, and rotations in 0.18$^\circ$ ~ 0.2$^\circ$ increments through 180$^\circ$. Reconstructed images were compared with images from histology slides obtained from the same samples. In this study, a new 3D histology technique using synchrotron micro tomography was established and applied to the analysis of the 3D structure of a mouse eyeball.

The internal electric field ($F$) of GaAs solar cells (SC) with different doping concentrations of the emitter layers has been investigated by using photoreflectance (PR) spectroscopy. At room temperature, the $F$ of the highly doped SC (HDSC) is 91.5 kV/cm, which is lower than the 6.3 kV/cm for the low-doping SC (LDSC). From the excitation-light-intensity ($I_{ex}$)-dependent PR, the drop in $F$ is about 20 kV/cm, which is larger than the theoretical value. The large drop in $F$ in the HDSC is confirmed to have been caused by an enhancement of the field screening effect resulting from the higher potential barrier effect of the window layer. Also, in the case of the LDSC, the rapid decrease in $F$ with decreasing temperature can be explained by a change in the height of the potential barrier.
