Abstract
X-ray scattering is used to probe the smectic order in octylcyanobiphe nyl partially confined between a free surface and a microgrooved glass substrate. It is found that the smectic order develops 6 K above the bulk nematic to smectic-A transition with layer spacing compressed up to 3% under a lateral confinement within the grooves. This lateral con finement is released as the thickness of the film above the grooves in creases.
