비정합 결정구조를 갖는 $(LaS)_xVS_2(x\approx 1.18)$의 결정구조적 특성연구 = Structural Characterization of Incommensurate Misfit Layer Compound $(LaS)_xVS_2(x\approx 1.18)$

다국어 초록 (Multilingual Abstract)

Single crystals of misfit layered (LaS)xVS2(x 1.18) were grown using LaCl3(or I2) as a mineralizer (or transport agent) for the single crystal X-ray diffraction analysis. Procession photographs of (LaS)xVS2(x 1.18) were analyzed as the stacking structure of two kinds of LaS-and VS2-subcell. The result shows that two sublattices have common periodicities along the a*-and c*-axes, respectively, but not along the b*-axis. Sublattice dimensions of LaS and VS2 layers along b-axis were 5.67$\AA$ and 3.42$\AA$, respectively. Their ratio was 1.657 which is very close to 5/3.
