Set ups to probe the response to external electric fields (FZJ-ICS3)
Light Scattering
Description
Homebuilt small angle (1-10/um) dynamic light scattering is equipped vertically to the sample stage, and with an in-situ electric field (AC field, +/- 200 V, 1Hz-300kHz). The in-situ electric cell consists of two ITO plates, separated by a Teflon spacer, which are connected to an AC-voltage generator. This cell can be also used in a microscope, as well as a vertical DLS set-up and the birefringence set up [1]. For the electric-birefringence, a null-birefringence set-up with an oblique incident laser beam enables probing the birefringence of samples with anisotropy of the refractive index that is perpendicular to the walls of the sample cell.
