摘要
The sputtering yields of a GaAs single crystal with (100) orientation bombarded by 15-35 kev**4**0Ar** plus for normal incidence are determined. The yield values are compared with different modifications of P Sigmund's sputtering yield formula in the elastic collision region. The atomic surface binding energy of GaAs is estimated using the measured yield values. The results are compared with that of metallic alloy sputtering and the qualitative differences are noted.
