摘要
The temperature dependence of the sputtering behaviour of various low-Z materials is presented. The hydrocarbon production under deuterium bombardment is investigated as a function of the target temperature. Carbon doped with beryllium or boron, as well as boron carbide show a strong reduction in the chemical sputtering yield. The reduction of the radiation-enhanced sublimation yield (RES) above 1200 K is small and not uniquely correlated with the dopant concentration. A variety of doped graphites is compared for 1 keV D+ sputtering at 300, 800 and 1470 K. The resulting erosion yields are discussed in terms of dopant concentration and the microstructure of the materials.
