The I-V curve is below -- more current when more light is shining on them! Also, strangely non-linear behaviour -- perhaps a schottky barrier at one end between the Pt-Si.
short wire (1.3 μm) -- massive photoresponse at saturation. The sample was gently shaded with Al foil, still a lot of light leaking in for the dark curve, and just room light for the light curve (more current)
Unfortunately the contacts melted during annealing, but we might yet be able to fix that.
