Abstract As the doped semiconductors can induce and tune the novel physical characteristics. Therefore, we present the investigation of Fe doped SnS nano-crystallites, with xFe = 0.00–0.10, synthesized by using cost-effective and simple co-precipitation method. X-ray diffraction (XRD) has confirmed the orthorhombic single phase formation with nano-crystalline nature that is consistent with the surface structure revealed using SEM. NEXAFS spectroscopy has demonstrated that Fe retains +2 oxidation states. The dielectric response measured within 1 kHz-20 MHz depicts that the specimens respond well to the low energies indicating potential applications in the optical devices. Complex impedance study has elucidated dominant contribution from the grain resistance, while the complex modulus analysis confirmed the role of grains capacitance, suggesting that the polarization effect of such electrodes could have practical utilities. The ferromagnetism exhibited at 300 K also has revealed data storage device applications of the studied compounds.

用于自旋电子应用的 SnS:Fe 稀磁半导体纳米粒子的物理性质研究

摘要 由于掺杂半导体可以诱导和调节新的物理特性。因此，我们研究了使用具有成本效益且简单的共沉淀方法合成的 Fe 掺杂的 SnS 纳米微晶，其中 xFe = 0.00-0.10。X 射线衍射 (XRD) 已证实具有纳米晶体性质的正交单相形成，这与使用 SEM 显示的表面结构一致。NEXAFS 光谱已证明 Fe 保留 +2 氧化态。在 1 kHz-20 MHz 范围内测量的介电响应表明样品对低能量响应良好，表明在光学器件中的潜在应用。复阻抗研究阐明了晶粒电阻的主要贡献，而复模量分析证​​实了晶粒电容的作用，表明这种电极的极化效应可能具有实用价值。在 300 K 下表现出的铁磁性也揭示了所研究化合物的数据存储设备应用。
