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...

We studied the hydrothermal growth condition of ZnO nanostructure arrays on p-GaN substrates that could be used as light-emitting diode (LED) pixel arrays for bioimage sensors. The ZnO nanostructures were grown in the forms of either nanorods or nanoflowers at different substrate temperatures during the ZnO seed-layer deposition. We found that flower-shaped ZnO nanostructures and ZnO nanorods were grown when a rough seed layer and a smooth seed-layer were formed at temperatures lower and higher than 500 $^\circ$C, respectively. With low seed-layer growth temperatures, a rough surface was formed, provided numerous nucleation sites in patterned holes, and produced dense flower-shaped nanostructures. On the other hands, with high seed-layer growth temperatures, a smooth seed-layer surface was formed and provided nucleation sites for ZnO nanorod growth.

Study of the Shapes of CdSe/CdS Nanocrystals by Using Raman Spectroscopy and the Stokes Shift

In order to obtain data on the formation process of CdSe/CdS core/shell semiconductor nanocrystals, we subjected samples of nanocrystals to long-term heat treatment at a temperature of 80 $^\circ$C. After a certain time, the absorption and the emission spectra were measured using parts of the samples. As the heat treatment time was increased, the Stokes shift decreased until the growth of the CdSe nanocrystals stopped. The time when the Stokes shift increases after a certain time can be regarded as the time when the surfaces of nanocrystals change. A method for distinguishing whether CdSe/CdS has core-shell structure or is an alloy was studied by analyzing the Raman spectra and the X-ray diffraction (XRD) patterns of the samples at the time when the surfaces of the nanocrystals changed. When CdSe/CdS core-shell semiconductor nanocrystals are synthesized, a chance exists that interfaces will be observed in CdS$_x$Se$_{1-x}$ alloys. Thus, distinguishing whether the synthesized nanocrystals have a core-shell structure or are CdS$_x$Se$_{1-x}$ alloys is possible. If a new phonon is observed between phonon L01 and phonon L02 in the Raman spectra, the material is an alloy. A more precise core-shell structure can be identified by looking at the XRD pattern and the Stokes shift.
