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...

Plane-Wave Density Functional Theory Study of the Electronic and the Structural Properties of Ionized and Neutral Small Gold Clusters
Byeong June MIN*

Au clusters and their ions are notable catalysts with a strong size dependency. We studied the structural and the electronic properties of ionized and neutral small gold clusters (${Au_n}$, ${Au_n^+}$, ${Au_n^-}$, n = 2 $\sim$ 8) via plane-wave pseudopotential calculations. All except ${Au_7^-}$ favor a one-dimensional zigzag structure or a two-dimensional arrangement of triangles. The HOMO-LUMO (highest occupied molecular orbital – lowest unoccupied molecular orbital) gap, the ionization energy, and the electron affinity exhibit even-odd variations as functions of the cluster size. The net spin density isosurfaces of the magnetic clusters are also presented.

We investigated the origin of the reduction in the junction electric field of an InAs/GaAs quantum-dot solar cell (QDSC) by using photoreflectance (PR) spectroscopy. From the PR results with various excitation intensities ($I_{ex}$), the PR spectra clearly exhibited an oscillatory feature related to Franz-Keldysh oscillations (FKOs) due to the p-n junction electric field ($F_{pn}$). The strength of the $F_{pn}$ in the InAs/GaAs QDSC with various $I_{ex}$ was lower than that of the GaAs single-junction SC. The difference in the $F_{pn}$ ($\Delta F_{pn}$) between the GaAs single-junction solar cell and the InAs/GaAs QD solar cell with low $I_{ex}$ is about 34 kV/cm. This result can be explained by a decrease in the carrier concentration ($N_d$) in the n-GaAs absorption layer. To confirm the reduction of $N_d$ in the QDSC, we calculated the variation in the maximum electric field ($\Delta F_{max}$) in a p-n junction with various carrier concentration losses. When the carrier concentration loss in the QDSC was increased by 28%, the calculated $\Delta F_{max}$ coincided exactly with measured $\Delta F_{pn}$ from the PR results. The decreased $N_d$ in the InAs/GaAs QDSC is attributed to a decrease in the electric field strength due to the carrier trapping and re-capturing processes in the defect and QD states.
