Structural, dielectric and ferromagnetic properties of nano-crystalline Co-doped SnS
Source abstract
Abstract
Doping-induced tuning of host semiconductors properties offers an efficient way to realize the desired physical properties. In this study, we have synthesized pure and Co-doped SnS-diluted magnetic semiconductors with x Co = 0.00–0.10, by employing a very simple and low-cost chemical co-precipitation technique. The structural properties, determined through X-ray diffraction, have confirmed single-phase orthorhombic structure and have depicted nano-crystallites. Near-edge X-ray absorption fine structure spectroscopy has revealed a Co-doping-induced shift in the absorption edge towards lower energy, indicating a change in the Co oxidation state. Surface morphology observed through scanning electron microscopy indicates nano-structured surface. Dielectric properties measured by impedance analyzer (LCR meter) in the frequency range 1 kHz–20 MHz depict that grown materials respond to the electromagnetic radiations suggesting potential device applications. Complex impedance spectroscopy illustrates the dominance of grain resistance. The magnetic properties observed by vibrating sample magnetometer reveal room temperature ferromagnetism, and Co ions inducing tuning of the ferromagnetism suggests potential applications in the data storage devices.
