Supercapacitors have advantages such as excellent power density, fast charge and discharge times, long life cycle, and relatively low cost which make them likely to replace other energy storage options. Semi-metallic (1T` phase) molybdenum ditelluride (MoTe2) has recently been considered as a promising candidate for an electrode in supercapacitors due to high mobility (3900cm2/Vs) with low carrier concentration (ne ≈ 2.3 x 1020 cm-3) from MoTe2 powders and flakes. Thus, an efficient fabrication technique for MoTe2 electrodes with high electrical properties for supercapacitor application is needed. Here we employed two-step method of magnetron sputtering followed by chemical vapor deposition (CVD) to synthesize a few-layer 1T`MoTe2 electrode to be used in a supercapacitor.
