b) Fig. Q2 shows a plot of the sputter yield versus bombarding energy for the sputtering of a number of different materials (zinc, copper, aluminium, silicon and titanium) by argon ions. 10 Zn Cu AI Si 물 Ti Sputter yield 0.1 0.01 10 100 100,000 1000 10,000 lon enerav (ev) Fig. 22. 2 i) ii) iii) 2 2 Define the term sputter yield in terms of particle fluxes Why do the sputter yields start to decrease at very high ion energy? At 1000 eV bombarding energy why is the sputter yield of zinc much higher than that of titanium? What is the sputter yield of titanium when the bombarding argon ion velocity is 6.95 x 104 ms-?? iv) 4
