摘要 | Vanadium nitride (VN) thin films with high specific capacitance are desirable in microsupercapacitors. Considering the integration with the silicon-based microelectronics, VN thin films on silicon wafers are needed. Here, hierarchical-porous VN thin films are deposited on silicon wafers through a solution-processable method. The prepared VN/silicon thin films show a high areal specific capacitance of similar to 60 mF cm(-2) at 5 mV s(-1) in 1 M KOH electrolyte. Symmetric devices deliver a high energy density of 21.2 and 12.8 mWh cm(-3) at a power density of 2.0 and 16.8 W cm(-3), respectively. Excellent retention 91.2% is achieved after 15,000 cycles. The results will provide a solution method for preparation of hierarchical-porous VN thin films on silicon wafers with excellent performance. |
