Sputter depth profiling of Mo/B4C/Si and Mo/Si multilayer nanostructures: A round-robin characterization by different techniques (original) (raw)

Ion beam shadowing effects in SIMS depth profile analysis of MBE-grown nanostructures

Vacuum, 2005

Ion beam sputtering of molecular beam epitaxy (MBE) grown laser heterostructures was performed in the secondary ion mass spectrometry (SIMS) depth profile analysis. The layered structures In0.24Al0.19Ga0.57As/Al0.25Ga0.75As/GaAs were bombarded with Ar+ ion beam of two energies 5000 and 880eV and several current densities. For the examined 4-μm-thick laser structures we obtained the depth profile resolution Δz16–84%=7nm measured from the rising
