Stressed Silicon Nitride Membrane with Nickel Nanoparticles
An extremely thin (30nm) free standing silicon nitride membrane with nickel nanoparticles, following
heating with a short laser pulse. The nanoparticles react with the substrate, and the induced stress in
the film creates large ripples in the membrane surface. 90µm scan. Imaged with a MFP-3D AFM.
