The continuum theory of director fluctuations in nematic liquid crystals is extended to take account of finite sample size which more accurately describes experiments on thin films. The effect of external fields on director fluctuations is considered for two cell geometries: (i) the field parallel to the director for materials of positive susceptibility anisotropy, and (ii) the field perpendicular to the director for materials of negative susceptibility anisotropy. In the latter geometry, quenching of fluctuations leads to induced biaxiality. Comparison with experimental results shows that even allowing for the finite size of the sample, there is still a significant disagreement between theory and experiment, especially from thin samples. |
