Carbon vacancies regulation strategy for boosting the high-temperature microwave absorption performance of (Co0.2Mo0.2V0.2Nb0.2Ta0.2)Cx high-entropy carbides

The microwave absorption performance of (Co 0.2 Mo 0.2 V 0.2 Nb 0.2 Ta 0.2 )C x high-entropy carbides prepared by ball milling is optimized by modulating the concentration of carbon vacancies.
