| 摘 要： | Low-Z materials, such as carbon-based materials and Be, are major plasma-facingmaterial (PFM) for current, even in future fusion devices. In this paper, a new type ofmultielement-doped carbon-based materials developed are presented along with experimental re-sults of their properties. The results indicate a decrease in chemical sputtering yield by one orderof magnitude, a decrease in both thermal shock resistance and radiation-enhanced sublimation, anevidently lower temperature desorption spectrum, and combined properties of exposing to plasma.
