Pretilt can be tuned up using obliquely evaporated inorganic oxides as alignment surface. A thorough study of pretilt angles induced by aligning surfaces of thermally evaporated SiO has been carried out on several commercial and experimental negative nematic mixtures. Morphology of SiO with different evaporation angles has been studied by Field Emission Scanning Electron Microscopy. Some morphological variations appear at specific evaporation angles. These are related to the pretilt induced by the surface and to the dynamic response of the device. 1551-319X 10.1109/JDT.2010.2049730 https://hdl.handle.net/20.500.14352/42085 http://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=9425 Dynamics and Electrooptics of Vertically Aligned Nematics With Induced Pretilt on SiOx
