Abstract

Cubic SiC is one of the emerging semiconductors utilized in power and electronic devices. In this work, 3C-SiC was tuned to protonic conducting properties via constructing an n–p heterostructure composite with Na0.6CoO2 (NCO). The peak power density of the fuel cell with 1:1.5 3C-SiC/NCO as an electrolyte is 251.6 mW cm–2, while its corresponding ionic conductivity reaches 0.12 S cm−1 at 550 °C. The band alignment and local electric field at the interface are simulated to explain the 3C-SiC/NCO conducting mechanism and device electrochemical performances. This research indicates that 3C-SiC can be modulated to proton conducting material through a semiconductor heterostructure interface mechanism.
