    Abstract Photoinduced voltages associated with surface plasmon polariton excitations are studied both theoretically and experimentally in various plasmonic systems as the function of material, wavelength, and type of structure. Experimental photovoltage normalized to the absorbed power shows a general decrease upon an increase in the wavelength, enhancement in the nanostructured samples, and a strong variation in the magnitude as a function of the material, which are not in line with the theoretical predictions of the simple plasmonic pressure approach. The results can be used for clarification of the mechanisms and further development of an adequate theoretical approach to the plasmon drag effect.

    Plasmon-enhanced photovoltages in 1D profile-modulated permalloy films strongly depend on magnetic field, with a characteristic hysteresis. The effect is discussed in terms of the anomalous Nernst effect.

    Photogeneration of significant electrical voltages observed in plasmonic metasurfaces is promising for applications in plasmon-based electronics and plasmonic sensors with compact electrical detection. In order to better understand the role of the surface geometry, we study photoinduced electrical effects in profile-modulated plasmonic surfaces. Photoinduced voltages in strongly modulated plasmonic surfaces demonstrate highly asymmetric angular dependence with polarity switching at the plasmon resonance conditions. The effects are attributed to coupling between localized and propagating plasmons and discussed in the frame of the electromagnetic momentum loss approach.
