Non-steady-state photo-electromotive force effect in selenium nanowire array within chrysotile asbestos matrix

In this work, the frequency transfer functions of the non-steady-state photo-electromotove force (EMF) signal in selenium nanowire array within chrysotile asbestos matrix is measured in the "longitudinal" and "transversal" geometries of the experiments. The anisotropy of the studied material reveals not only in the difference of the current amplitude along and across nanowires but also in the experiments with varied light polarization. The higher signal amplitudes are observed in the case when the light is polarized perpendicular to nanowires.
