dc.description.abstract | The orientation of nematic liquid crystal (LC) E7 on the surface of (111) silicon wafers and in the channels of grooved
silicon structure has been investigated. Grooved Si is a periodical structure obtained by wet anisotropic etching of deep
and narrow grooves in (110) Si using an alkaline solution. This structure can serve as a one-dimensional (1D) photonic
crystal. Composite structures obtained from grooved Si infiltrated by LC are promising candidates for electro-optic
application. LC E7 was infiltrated into the channels of grooved Si and into the bulk Si cells. IR spectroscopy and
capacitance-voltage characteristics under DC electric field were applied to investigate LC orientation. It is shown that
the E7 liquid crystal in grooved silicon exhibits a weak planar orientation with respect to the silicon walls. | en |
