Abstract [en]

We describe the effect of optical excitation of state of the art nonvolatile memory capacitors. The devices comprise Au nanocrystals sandwiched between a SiO2 tunneling layer and a HfO2 blocking layer and exhibit an effective oxide thickness of 7.5 nm. The memory properties are modified by the optical excitation due to nonequilibrium depletion. Optical control with different illumination wavelengths as well as variable optical intensities and pulse widths is described. (C) 2011 American Institute of Physics. [doi:10.1063/1.3543620]
