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...

Li$_2$Sr$_{1-x}$Eu$_x$SiO$_{4-\alpha}$N$_\alpha$ (Li$_2$SrSiO$_{4-\alpha}$N$_\alpha$:Eu$^{2+}$) phosphors were synthesized by using a solid state reaction (SSR) method with submicron Si$_3$N$_4$ and nano Si$_3$N$_4$ powders as the sources of Si and N, and the optical properties of those phosphors were studied. The studied phosphors showed efficient excitation characteristics over the broad range from 230 to 530 nm. Also, They showed broad emission spectra covering a range from 500 to 700 nm, with a peak at 568 nm, which was shifted longer wavelength by 18 nm as compared with that of commercial YAG:Ce$^{3+}$. Combined with a 450 nm blue LED chip, the results support the application of the Li$_2$SrSiO$_{4-\alpha}$N$_\alpha$:Eu$^{2+}$ phosphor as a luminescent material for a white-light source thaat is warmer than the commercial YAG:Ce$^{3+}$ white-light source. In addition, the Li$_2$SrSiO$_{4-\alpha}$N$_\alpha$ phosphors prepared from a submicron Si$_3$N$_4$ powder was found to emit a previously unreported self-activated luminescence in Li$_2$SrSiO$_{4-\alpha}$N$_\alpha$.

Optical Properties of Plasmons in a GaAs/Al$_x$Ga$_{1-x}$As Multiple Quantum Well Under Electric and Magnetic Fields

The plasmon behaviors in a superlattice of GaAs/Al$_x$Ga$_{1-x}$As multiple quantum wells with a half-parabolic confining potential due to different dielectric interfaces are studied under magnetic and electric fields perpendicular and parallel to the superlattice axis by using a previously published theoretical framework. From the density-density correlation functions by considering the intrasubband and the inter-subband transitions under the random phase approximation, we calculate the dispersion energies of the surface and the bulk states as functions of the composition of the multiple quantum well structure and of the magnetic field strength and the average electric field strength over the quantum well. The Raman intensities for various magnetic field strengths and average electric field strengths over the quantum well are also obtained as a function of the energy of the incoming light for these states.
