Domains walls of ferroelectric domains in RbHSO4 measured at -30°C

RbHSO4 single crystal, z.cut Domains walls of ferroelectric domains in RbHSO4 measured at -30°C with the help of an home build cooling stage. Bright and dark areas correspond to a forward or backward sheer motion of the crystal. Polarrization is oriented ou-of-plane with the bubbles beeing positively polarized.
