Energy storage performance of 2D MoS
Compared to 2H MoS 2, the composite 2H MoS 2 /MWCNT has a high energy density (28.36 Wh kg −1) at higher power density (3.19 kW kg −1). It also retains an energy density of about 20.70 Wh kg −1 at a power density of 1.49 kW kg −1, which indicates a significant potential use of 2H MoS 2 /MWCNT for supercapacitors.

Power MOSFET Maximum Ratings
For power MOSFETs, maximum ratings are defined using an absolute maximum rating system. Maximum ratings are the highest absolute values that must not be exceeded even instantaneously under any conditions. A device ma y not be able to recover from stress that exceeds a specified maximum rating.

Power MOSFET Electrical Characteristics
Gate current flows from gate to source instantaneously to charge the input capacitance. Therefore, the lower the output impedance of the drive circuit, the faster the switching speed. Large input capacitance of a MOSFET causes a large power loss at light load. Ciss, Crss and Coss hardly vary with temperature.
