Abstract
In our current study, we have investigated the effect of potassium doping on AC conductivity and the dielectric properties of tin selenide (SnSe). Potassium-doped SnSe (KxSn1-xSe with x = 0–20 mol%) polycrystals were synthesized via hydrothermal method. The phase of the synthesized samples was confirmed to be single phase with orthorhombic structure as obtained by X-ray diffraction. The average crystallite size for all the KxSn1-xSe samples was calculated using the Debye–Scherrer formula and they were found to be decreased as potassium (K) concentration increased. Scanning electron microscope revealed plate-like morphology for all KxSn1-xSe samples. Transmission electron microscope studies at high resolution showed plate-like morphology which is connected with small nanorods for the K0.20Sn0.80Se. Optical studies were carried out using UV–Vis–NIR diffuse reflectance spectroscopy. The bandgap values were found to be decreased as K concentration is increased. Temperature-dependent dielectric studies were studied for all KxSn1-xSe samples. Correlated barrier hopping is responsible for the transport of charge carriers in the conduction mechanism. Electrical modulus studies reveal a non-Debye-type dielectric relaxation phenomenon. The results of dielectric studies specify the application of K-doped SnSe in frequency related and capacitive storage devices.
