TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The columns are aligned uniaxially, with their longitudinal axes aligned (roughly) parallel. The parts of the electrode array are at least two preferably at least three electrode fingers. The electrode fingers form comb-like structure(s). The electrode fingers preferably form two comb-like structures interdigitating with each other, or comb-like structure and meander-like structure interdigitating with each other. The two comb-like structures lie opposite each other with the electrode fingers of each comb-like structure facing each other. The electrode array is made of metal oxide(s) and/or metal. The electrode array is preferably made of at least two metals. The metal oxide(s) and/or metal are selected to match the work function of the electronic device. The metal(s) and/or metal oxide(s) is gold, silver, aluminum, ion, copper, platinum, zinc, tin, calcium, magnesium, indium doped tin oxide (ITO), fluorine doped tin oxide (FTO), doped zinc oxide (ZnO), or undoped zinc oxide (ZnO). There are at least two layers of the same or different discotic liquid crystalline material. One layer is on top of the other layer of discotic liquid crystalline material. The substrate is glass, quartz, flexible substrates (e.g. polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyether-sulfone (PES), stainless steel), or silicon. The substrate has been surface modified to achieve uni-axial alignment.Preferred Properties: The average distance between two adjacent electrode fingers is 1-100, preferably 3-10 micro-m.Preferred Methods: The uniaxial alignment is made by doctor blading, shearing, rubbing, zone casting and/or orientation by laser irradiation, exposition to magnetic field, drop casting, spin coating, Langmuir-Blodgett-techniques, Langmuir-Schafer-techniques, self-assembling of or at unmodified and/or modified substrate. The second and third steps are in reverse order. The uniaxial alignment occurs after or concomitantly with the second step.
