By the use of a deceleration electrode in the primary beam line of a magnetic sector SIMS instrument, an O 2 primary beam of variable energy and angle has been produced. The SIMS measurements of ultrathin Ge and B layers in Si were performed with low-energy (0.7-2 keV) and grazingly incident (50-75Γ

The Ge concentration in MBE-grown SiGe quantum wells can be quantitatively and non-destructively analyzed by means of low energy Rutherford backscattering (RBS), even for a 10 nm thick quantum well at a depth of about 60 nm below the surface. From the raw data quantitative information can be deduced
