Polarization-sensitive photoconductivity in aligned polyfluorene layers
Polarization-sensitive photodiodes have been constructed utilizing an aligned polyfluorene layer oriented on a photoaligned liquid crystalline photoaddressable polymer. The diodes exhibit a pronounced dependence of the photocurrent on the polarization of the incident light, yielding a polarization s...

| description | Polarization-sensitive photodiodes have been constructed utilizing an aligned polyfluorene layer oriented on a photoaligned liquid crystalline photoaddressable polymer. The diodes exhibit a pronounced dependence of the photocurrent on the polarization of the incident light, yielding a polarization sensitivity of more than a factor of 10 at the onset of the absorption. The action spectrum is symbatic for light polarized perpendicular to the polymer alignment direction whereas it does not simply correlate with the absorption characteristics for parallel polarized light. The data can be explained utilizing Ghosh’s model taking into account interference effects within the polyfluorene layer. |
