Abstract

Electrical transport in polycrystalline and single-crystalline (LaS)_1+δ(NbS₂) misfit-layered compounds was measured. Polycrystalline samples were synthesized using S raw materials of different purities (2N or 6N), and single-crystalline samples were grown using two types of transport agents (2NH₄Cl + PbCl₂ or NH₄Cl) via the chemical vapor transport method. The temperature dependence on resistivity dropped at ∼1.3–2.0 K for some of the samples, which might be affected by the unknown impurity. (LaS)_1+δ(NbS₂) misfit-layered compounds for the main phase of those obtained samples exhibited no superconductivity above 0.2 K by the resistivity measurement.

（LaS）1+δ(NbS2)错配层化合物的物理性质

测定了多晶和单晶（LaS）1+δ(NbS2)错配层化合物中的电输运。采用不同纯度的S原料（2N或6N）合成多晶样品，采用化学气相输运法分别用两种输运剂（2NH4Cl + PbCl2或NH4Cl）生长单晶样品。部分样品的电阻率温度依赖性在~ 1.3 ~ 2.0 K时下降，这可能受到未知杂质的影响。通过电阻率测量，所得样品的主相（LaS）1+δ(NbS2)错配层状化合物在0.2 K以上无超导性。

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
