Abstract:
MoS$_2$ nanostructures were prepared using the hydrothermal method by reacting ammonium heptamolybdate tetrahydrate ((NH$_4$)$_6$Mo$_7$O$_{24}$4H$_2$O) with citric acid monohydrate (C$_6$H$_8$O$_7$H$_2$O) in distilled water with the presence of sodium sulfide (Na$_2$S). The surface structure studies of MoS$_2$ showed that the size of the surface clusters of the studied tablet is of the order of 50 – 100 nm. Using measurements (Zetasizer Nano Series), we found that the particle sizes ranged from 150 – 350 nm. Alternating current (LCR) measurements were made for (tablet-MoS$_2$) under a constant temperature $T$ = 10$^\circ$C. Measurements of the parallel electrical capacitance $(C_p)$ in terms of frequency $(F)$ of tablet-MoS$_2$ showed a sharp drop in the value of the electrical capacitance $(C_p)$ with an increase in frequency within the range 20 Hz – 16 kHz. It is shown that the series capacitance increased with the increase of the applied potential.
