Dynamics and Electrooptics of Vertically Aligned Nematics With Induced Pretilt on SiOx Otón Martínez, Eva López De Andrés, María Sol Carrasco Vela, Carlos Cerrolaza, Beatriz Bennis, Noureddine Otón Sánchez, José Manuel The response time and contrast of vertically-aligned negative nematics depend critically on the aligning surface and its induced pretilt. 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. 2023-06-20T00:08:58Z 2023-06-20T00:08:58Z 2010 journal article 1551-319X 10.1109/JDT.2010.2049730 https://hdl.handle.net/20.500.14352/42085 http://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=9425 eng open access Institute of Electrical and Electronics Engineers.
