Abstract

Alloying of In/Zn oxides with various X atoms stabilizes the IXZO structures but generates electron traps in the compounds, degrading the electron mobility. To assess whether the latter is linked to the oxygen affinity or the ionic radius, of the X element, several IXZO samples are synthesized by the sol-gel process, with a large number (14) of X elements. The IXZOs are characterized by XPS, SIMS, DRX, and UV-spectroscopy and used for fabricating thin film transistors. Channel mobility and the interface defect density NST, extracted from the TFT electrical characteristics and low frequency noise, followed an increasing trend and the values of mobility and NST are linked by an exponential relation. The highest mobility (8.5 cm2/Vs) is obtained in In-Ga-Zn-O, and slightly lower value for Sb and Sn-doped IXZOs, with NST is about 2E12 cm2/eV, close to that of the In-Zn-O reference TFT. This is explained by a higher electronegativity of Ga, Sb, and Sn than Zn and In, their ionic radius values being close to that of In and Zn. Consequently, Ga, Sb, and Sn induce weaker perturbations of In-O and Zn-O sequences in the sol-gel process, than the X elements having lower electronegativity and different ionic radius. The TFTs with X = Ca, Al, Ni and Cu exhibited the lowest mobility and NST > 1E13 cm2/eV, most likely because of metallic or oxide clusters formation.

Abstract

Thin film transistors, with channels composed of In-X-Zn oxides, IXZO, with X dopants: Ga, Sb, Be, Mg, Ag, Ca, Al, Ni, and Cu, were fabricated and their I-V characteristics were taken at selected temperatures in the 77KST, were extracted from the characteristics for each of the studied IXZOs. At higher T, the mobility follows the Arrhenius law with an upward distortion, increasing as T is lowered, gradually transforming into the exp [-(T0/T)1/4] variation. We showed that μ(T, NST) follows μ0 exp[-Eaeff(T,NST)/kT], with T-dependent effective activation energy Eaeff(T, NST) accounts for the data, revealing a linear correlation between Eaeff and NST at higher T. Temperature variation of Eaeff(T, NST) was evaluated using a model assuming a random distribution of conduction mobility edge Ec values in the oxides, stemming from spatial fluctuations induced by disorder in the interface traps distribution. For a Gaussian distribution of Ec, the activation energy Eaeff(T, NST) varies linearly with 1/T, which accounts satisfactorily for the data obtained on all the studied IXZOs. The model also shows that Eaeff(T, NST) is a linear function of NST at a fixed T, which explains the exponential decrease of μ with NST. [ABSTRACT FROM AUTHOR]

27. Direct evaluation of low-field mobility and access resistance in pentacene field-effect transistors.

Abstract

Organic field-effect transistors (OFETs) suffer from limitations such as low mobility of charge carriers and high access resistance. Direct and accurate evaluation of these quantities becomes crucial for understanding the OFETs properties. We introduce the Y function method (YFM) to pentacene OFETs. This method allows us to evaluate the low-field mobility without the access or contact resistance influence. The low-field mobility is shown to be more appropriate than the currently applied field-effect mobility for the OFETs’ performance evaluation. Its unique advantage is to directly suppress the contact resistance influence in individual transistors, although such contact resistance is a constant as compared to the widely accepted variable one with respect to the gate voltage. After a comparison in detail with the transmission-line method, the YFM proved to be a fast and precise alternative method for the contact resistance evaluation. At the same time, how the contact resistance affects the effective mobility and the field-effect mobility in organic transistors is also addressed. [ABSTRACT FROM AUTHOR]

Abstract

New strategies to improve the outcome of gene therapy often employ a nonviral gene delivery, which is most likely to fulfil microbiological safety criteria and be retained in the clinical setting. Here we show that efficient gene transfer can be achieved in vitro using as a vector a polyvalent peptide derived from the N-terminal sequence of the human adenovirus fiber protein. The level of transfection is better than that obtained with the two liposomes, DOTAP and DOSPER. Internalization was studied by confocal microscopy using fluorescently marked peptide and DNA. The peptide alone is targeted to the nucleus and concentrated within the nucleolus. Similarly, DNA complexed with peptide also enters the nucleolus, where it is retained for at least 48 h. Peptide I appears to attach to cells by a saturable process, as preincubation of cells with peptide blocks transfection and there is no transfection at 4 degrees C. The peptide contains three domains: a nuclear localization signal of adenovirus fiber protein; a domain containing hydrophobic and polar residues harboring an internalization signal for receptor-mediated endocytosis; and a stretch of lysines. Each of these domains is required for optimum gene transfer. Peptide I may be an interesting alternative to known vectors for gene transfer, for local administration and for ex vivo applications.

Abstract

In this brief, low-frequency noise (LFN) characteristics are studied in oxide-based (TiN/HfOx/Pt) resistive random access nemory cells having different dimensions. It is confirmed that, for the low resistance state (LRS), current conduction is localized without an area dependence, whereas for the high resistance state, it is a uniform leakage current throughout the whole device area. An LFN model is proposed for the filamentary LRS based on the carrier number fluctuation approach, allowing physical analysis of filament characteristics and the surrounding trap concentration.

Abstract

Each of the 12 vertices of the adenovirus virion is made of penton, the complex of two oligomeric proteins: a pentameric penton base anchored in the capsid and an antenna-like trimeric fiber extending outwards. Adenovirus penton plays an essential role in the infection of host cells because it is indispensable for virus attachment and internalization. The initial interactions of penton with the primary and secondary receptors are well described. In contrast with that, the role of the penton components downstream of the initial cell contact is not known. This work shows for the first time that two adenovirus structural proteins, fiber and base, are able to interact intimately with different classes of cellular targets. In the case of penton base, a protein responsible for virus internalization, the partners include three ubiquitin-protein ligases that are involved in protein turnover, cell cycle control and endocytosis. Another base protein partner, BAG3, is involved in controlling Hsc70 chaperone activity. Virus attachment protein, fiber, interacts with many different partners, some of them involved in signal transduction and cell growth. Further work will illustrate the implications of these interactions for both the viral and cellular life cycles.
