- The size of the smallest region which can be probed depends on the cell thickness and beam intensity. With a typical SSFLC cell (thickness t =2μm) and an 18KW rotating anode laboratory generator, sample areas greater than ≃ 3 mm × 3 mm are required for a reasonable signal. With a high intensity synchrotron diffractometer such as beamline VII-2 at SSRL, areas as small as 50 μm × 50 μm can be studied. Effective detection of the scattering from a micron thick liquid crystal layer between glass plates several hundred times thicker requires a diffractometer with sufficiently high angular resolution.
- This behavior is quite different from that found upon cooling a bulk sample through a second order SA to SC transition with a magnetic field applied. In the bulk case the director orients along the field direction, z, in the SA phase with the layers normal to z and having a pitch (length per layer along z) PA = d A Upon cooling into the SC phase, the layers tilt through the director tilt angle θ( T) < δ( T), implies pc < PA. In the bulk case then the increasing pitch as the temperature is lowered in the SC phase requires the loss of layers, a condition forced by the magnetic field induced orientation constraint on n.
