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.
