The comparison of optical and electronic properties between squarely and hexagonally arranged nano-porous layers and uniformly arranged nano-wired layers of aluminium and silver was presented. The nano-wired configuration exhibit 20 and 10% higher average transmittance in visible wavelength range in comparison to square and hexagonal nano-porous designs, respectively. The insignificant difference of the transmittance for aluminium and silver nano-porous and nano-wired layers is observed, when interpore/interwire distance is larger than wavelengths of incoming light. This difference becomes considerable at the interpore/interwire distance less than wavelengths of incoming light: silver nano-porous and nano-wired layers possess up to 27% higher transmittance in comparison to aluminium layers.

Formation of thin-film nanomaterials, promising for nanoelectronic applications, with a given structure based on octa-phenyl-2,3-naphthalocyaninato zinc.

One-step cost effective process of fabrication of a full inorganic nanostructured transparent conductive electrode and LC alignment layer has been developed. More specifically, the subject comprises a self-organized nanomesh of a valve metal, concomitant porous oxide layer with various functionality and electrochemical method of their fabrication. The nanomesh film is electrically conductive, optically transparent and flexible. It can be fabricated on a variety of substrates, including flexible and rigid substrates. High effective LC alignment layers based of nanostructured alumina can be fabricated at the same anodization process by special electro-chemical technique in sulfuric and oxalic acids to form a self ordered nanoporous structure of alumina which has a "vertical" surface area that prevails over the "horizontal" one even though Al film's thickness is small. The possibility to control distances between pores and their sizes during the process of anodizing/etching enables to optimize alignment surface according to the required LC material.

. Moreover, alternative TCLs should be preferably flexible and have low cost. Different materials such as carbon nanotubes [4,5], graphene layers [6,7], zinc oxides [8], organic polymers [9], ultra thin metallic layers [10,11] and metallic nanogratings [12][13][14][15] were proposed as possible TCL candidates. But so far none of them has been adopted to replace the ITO [4][5][6][7][8][9]. Thin metallic layers of 10-50 nm thickness are the simplest flexible TCLs which can transmit up to 50% of incoming light in the visible spectrum [16]. Modifying these metallic layers to nanogratings can improve their opto-electronic performance up to that of ITO [14,[17][18][19][20]. The fabrication process of nanogratings includes lithography, nanoimprinting, and solution-processing. This paper presents a nonlithographic method of the fabrication of nanoporous Al TCLs. The transparent conductive nanomesh (or nanograting) was made by electrochemical anodizing of Al
