To improve electrical properties a high temperature annealing treatment was applied to several transparent conductive oxides (TCO), namely tin doped indium oxide (ITO), Ga- or Al- ZnO (ZnO:Al/Ga), ion beam assisted deposited (IBAD) ZnO:Ga and Ga zinc magnesium (ZnMgO:Ga). All these films were grown by magnetron sputtering. During the process all TCO capped with 50 nm of amorphous silicon in order protect from environmental impact. Increase mobility up 72 cm2/Vs low resistivity 1.6 × 10−4 Ωcm...

Ion beam assisted deposition (IBAD) is a promising technique for improving the material quality of ZnO-based thin films. The operation an auxiliary Ar+ ion source during ZnO : Ga films by dc magnetron sputtering led to improvement in crystalline texture, especially at low temperatures due momentum transfer from ions growing film. Etching IBAD-ZnO diluted HCl revealed crater-like surface structures with crater diameters up 600 nm. These are usually achieved after high substrate temperatures....

The optical and electrical properties of transparent conductive oxides (TCOs), traditionally used in thin-film silicon (TF-Si) solar cells as front-electrode materials, are interlinked, such that an increase TCO transparency is generally achieved at the cost reduced lateral conductance. Combining a highly front electrode moderate conductance with metal fingers to support charge collection well-established technique wafer-based technologies or for TF-Si substrate (n-i-p) configuration. Here,...

The cap at the 5'terminus of mRNA is a key determinant gene expression in eukaryotic cells, which among others required for dependent translation and protects from degradation. These properties are mediated by several proteins. One them 4E-Transporter (4E-T), plays an important role translational repression, decay P-bodies formation. 4E-T also one proteins that interact with initiation factor 4E (eIF4E), binding protein component machinery. molecular mechanisms underlying interactions these...

Abstract Malignant melanoma is a very aggressive tumour with the ability to metastasize at an early stage. Therefore, detection of great importance. Multiphoton tomography new non-invasive examination method in clinical diagnosis skin alterations that can be used for such diagnosis. In this paper, automated evaluation multiphoton images presented. The following features cellular and subcellular level were extracted differentiate between malignant melanomas, lesions, healthy skin: cell...

Two-photon microscopy enables high-resolution biomedical imaging as well photoluminescence lifetime investigations in photovoltaics. In order to provide a compact, highly flexible and cost-effective system, we present compact two-photon platform box with kagome hollow core photonics crystal fiber for laser pulse delivery. This is suitable the transmission of ultrashort IR pulses within two optical ranges (i) 700 nm 1000 (ii) 1400 1700 nm. Furthermore, two-beam arrangements parallel operation...
