Twist-grain boundary phase characterized by AFM technique
Original language description
Twist grain boundary (TGB) phases represent liquid crystalline systems with a regular array of defects. In our research we study a compound with stable TGBC phase and pursued its structure by various experimental techniques. We observed the surface of the smectic film by AFM microscope and detected a periodic relief. We found that the displacement amplitude is few nanometers with the periodicity about 500 nm. Such periodicity is in accordance with the periodicity of the TGBC blocks’ rotation estimated by polarizing microscopy. The surface modulation is explained by the deformation of TGBC structure, which is created on TGBC films. A simplified model interpreting the observed smectic surface displacement as the consequence of rotating TGBC blocks inside the sample is proposed.
