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...

Study of Nitrogen Plasma Treatment on Indium Tin Oxide Thin Films

We studied the effect of nitrogen plasma treatment on the indium-tin-oxide thin films. By monitoring the in-situ optical emission spectra during the capacitively coupled plasma treatments, we investigated the populations and the energies of the nitrogen plasma species. In particular, the nitrogen plasma consisting of excited neutral and ionic molecular species was studied and found to depend on the nitrogen flow. After the nitrogen plasma treatment, the optical band gap of the indium-tin -oxide thin films was reduced, and their resistance was increased. Interestingly, when the energy of the excited neutral molecular series became higher, the band tails increased but the sheet resistance was suppressed. We believe that co-generations of nitrogen doping species and oxygen vacancies by an energetic plasma were responsible for these results.

Dielectric Relaxation and ac Conductivity of Na/K Excess (Na$ _{0.53}$K$ _{0.47}$)(Nb$ _{0.55}$Ta$ _{0.45}$)O$ _{3}$ Piezoelectric Ceramics

We have prepared lead-free (Na$ _{0.53+x}$K$ _{0.47+x}$)(Nb$ _{0.55}$Ta$ _{0.45}$)O$ _{3}$ (NKNT) ceramics with Na/K excess by using a solid-state reaction method. To enhance the piezoelectric and dielectric properties of NKN based system, it is necessary to excess Na and K ions in A-sites. The dielectric and the piezoelectric properties were enhanced for $x$ = 0.005. We investigated the temperature and the frequency dependences of the dielectric response and the electrical conductivity. Cubic-tetragonal ($T_{c}$) and tetragonal-orthorhombic ($T_{O-T}$) phase transition were found at 148 $ ^{\circ}$C and 40 $ ^{\circ}$C, respectively. Especially, the piezoelectric-improved NKNT ceramic had a low-frequency dielectric dispersion and low electrical conductivity. We investigate the frequency and the temperature dependences of the complex dielectric response and the electrical conductivity for NKNT ceramics with an optimum Na/K excess.
