  • As the most widely used media of BtoB e-business, the e-Marketplace can be a way of BtoB e-buisness continuously in the age of c-Commerce with the functional collaborative integration between the e-Marketplace and corporate systems. Moreover, collaborative operations like QR, VMI and so on have shown a great efficiency in the area of BtoB supply chain management. However, some critical considerations are discussed in the selection of trade partners between the e-Marketplace and the SCM. In e-Marketplaces, the intermediation to select partnersusually focuses on the competitive process for lower price. However, in the SCM, the relationship with strategic alliance is more importantly addressed for efficiency. Considering the trend to c-Commerce in Internet commerce, the approach to the collaborative relationship in BtoB commerce has important meanings. In this paper, we proposed and appraised an architecture where the e-Marketplace can be an elelctronic functional method for the relationship based BtoB e-business from the viewpoint of SCM and c-Commerce.

  • 인터넷을 상업적으로 이용하는 하나의 형태로 최근 들어 전자상거래가 주목을 받고 있다. 현재 전자상거래 시장의 급속한 신장세에도 불구하고, BtoC를 기반으로 하는 전자상거래 쇼핑몰의 성장은 기대에 못 미치고 있다. 이러한 상황은 현재의 전자상거래 쇼핑몰 비즈니스 모델에 대한 평가를 통해 차세대 모델로의 질적인 변화를 필요로 하고 있다. 이에 따라 본 연구에서는 기존의 전자상거래 비즈니스 모델인 BtoB와 BtoC를 혼합한 지역 전자상거래 쇼핑몰에 적합한 새로운 형태의 BtoBC 전자상거래 비즈니스 모델을 제시하였다. 제안된 모델을 통하여 소비자와 생산자 사이의 원활한 전자상거래가 가능해질 수 있을 것이다.

  • ferroelectric perovskite의 ferroelectricity를 유지하기 위해서는 oxygen vacancy를 조절해야 한다. BTO의 경우 Ti-O(vacancy site)-Ti의 align 방향에 따라 두 종류의 vacancy가 존재하는데, Ti-O-Ti가 c-axis와 평행한 경우 BTO의 ferroelectricity가 약해진다. 본 연구에서는 BTO에 ab-biaxial strain을 가해 보고, 그 결과 두 종류의 vacancy formation energy가 어떻게 변화하는지 확인하였다. 그 결과 a, b-axis의 격자 상수가 증가하면 $V_b$$V_c$에 비해 안정해진다는 사실을 확인하였다. 이는 BTO의 oxygen vacancy의 vacancy site에 vacancy로 인해 남는 전자가 국지화되어 Ti-vacancy site 간 인력과 Ti-Ti간 반발력이 균형을 이룰 때 vacancy의 에너지가 낮아지기 때문이다.

  • In this study, the sputtered BTO film was polished by CMP process with the self-developed $BaTiO_3$- and $TiO_2$-mixed abrasives slurries (MAS), respectively. The removal rate of BTO ($BaTiO_3$) thin film using the $BaTiO_3$-mixed abrasive slurry (BTO-MAS) was higher than that using the $TiO_2$-mixed abrasives slurry ($TiO_2$-MAS) in the same concentrations. The maximum removal rate of BTO thin film was 848 nm/min with an addition of $BaTiO_3$ abrasive at the concentration of 3 wt%. The sufficient within-wafer non-uniformity (WIWNU%) below 5% was obtained in each abrsive at all concentrations. The surface morphology of polished BTO thin film was investigated by atomic force microscopy (AFM).

  • Artificial $BaTiO_3$(BTO)/$SrTiO_3$(STO) oxide superlattice have been deposited on MgO (100) single crystal substrate by pulsed laser deposition(PLD) method. The stacking periodicity of BTO/STO superlattice structure was varied from $BTO_{1\;unit\; cell}/STO_{1\;unit\; cell}$ to $BTO_{125\;unit\; cell}/STO_{125 \;unit \;cell}$ thickness with the total thickness of 100 nm. The result of X-ray diffraction showed the characteristics of superlattice in the BTO/STO multilayer structure. we have also confirmed that there was no interdiffusion at the interface between BTO and STO layers by high resolution transmission electron microscopy(HRTEM). The dielectric constant of superlattice increased with decreasing stacking periodicity of the BTO/STO superlattice within the critical thickness. The dielectric constant of the BTO/STO superlattice reached a maximum i.e., 1230 at a stacking perioicity of $BTO_{2\;unit\; cell}/STO_{2\;unit\; cell}$ .

  • CoNiFe(CNF)/$BaTiO_3(BTO)$/CoNiFe(CNF) multilayered thin films were deposited on Pt/Ti/$SiO_2$/Si substrates by using pulsed laser deposition (PLD) system. We fabricated three different thin films of BTO, BTO/CNF and CNF/BTO/CNF for magneto-capacitor and studied their crystalline structure, surface and interface morphology, and magnetic and electrical properties. When three different structures of multilayered thin film were compared, magnetization of CNF/BTO/CNF thin films was decreased by magnetic and dielectric interaction. Also we confirmed that capacitance of CNF/BTO/CNF multilayered thin film was enhanced as being near tetragonal structure with increasing of c/a ratio because of atomic bonding at interface between BTO dielectric and CNF magnetic materials. Finally, we studied the change of the capacitance of CNF/BTO/CNF multilayered thin film with magnetic field for emergence of magnetocapacitance and suggested a possibility of enhanced capacitance.

  • Factor analysis was applied to study the thermal decomposition of barium titanyl oxalate (BTO) which is used as the precursor of barium titanate. BTO was synthesized in $H_2O$ solvent and calcined at various temperatures. The X-ray diffraction patterns were obtained to make the data matrix of peak intensity vs. 2${\theta}$. Abstract factor analysis and target transformation factor analysis were applied to this data matrix. It has been found that the synthesized BTO consists of the crystals of $BaC_2O_4{\cdot}0.5H_2O\;and\;BaC_2O_4{\cdot}2H_2O$ as well as the amorphous solid of TiO-oxalate. The results also indicate that the BTO was transformed via $BaCO_3\;to\;BaTiO_3\;and\;Ba_2TiO_4$ during the thermal decomposition.

  • Barium titanyl oxalate(BTO) was precipatated by utilizing the thermal decomposition of dimethyl oxalate in acidic aqueous solution having $BaCl_2$ and $TiCl_4$. Particle morphology of BTO was influeneced by the various experimental factors. i.e.. the faster rate to nucleation with higher temperature and the higher ratio of [DMO]/[$Ba^{2+}+Ti^{4+}$] was found to correspond to the faster rate of transformation of particle size distribution from unimodal to broad unimodal through bimodal. The BT powder obtained by calcination at $900^{\circ}C$ in air consists of larger particles than BT generated by general coprecipitation method and shows tetragonal symmetry. The stirring during reaction was also found to have much effect upon characteristics of BTO and BT.

  • Bismuth layered structure ferroelectric thin films, $Bi_4$$Ti_3$$O_{12}$ / (BTO) and Nb-doped BTO (BTN) were prepared on the Pt(111)/Ti/$SiO_2$/Si(100) substrates by a sol-gel route. We investigated the Nb-doping effect on the grain orientation and ferroelectric properties. $Nb^{5+}$ ion substitution for $Ti^{4+}$ ion in perovskite layers of BTO decreased the degree of c-axis orientation and increased the remanent polarization (2Pr). The fatigue resistance of Nb-doped BTO thin film was shown to be superior to that of BTO, and the leakage current of Nb-doped BTO thin film was decreased about 1 order of magnitude compared with BTO. The improvement of ferroelectric properties with $Nb^{5+}$ doping in BTO could be attributed to the changes in space charge densities and grain orientation in the thin film.
