Electrolyte gated thin film transistors (TFTs) based on sol–gel processed zinc oxide (ZnO) are investigated using imidazolium-based ionic liquids (ILs), namely [bmim][BF<sub>4</sub>] and [bmim][PF<sub>6</sub>], as electrolytes.
We study how partial monolayers of molecular dipoles at semiconductor/metal interfaces can affect electrical transport across these interfaces, using a series molecules with systematically varying dipole moment, adsorbed on n-GaAs, prior to Au or Pd metal contact deposition, by indirect evaporation as "ready-made" pads. From analyses the molecularly modified surfaces, we find that coverage is poorer low- than high-doped n-GaAs. Electrical charge resulting was studied...
Synthetic melanin based metal–insulator–semiconductor devices are fabricated for the first time thanks to silicon surface wettability modification by using dielectric barrier discharge plasma. Ambipolar charge trapping in air and ion drift mechanisms under vacuum identified capacitance–voltage hysteresis loops. These results aim foresee possible integration of synthetic layers as a novel capacitor organic polymer devices. Detailed facts importance specialist readers published "Supporting...
Abstract. In the last years disturbances in VLF/LF radio signals related to seismic activity have been presented. The data were collected by receivers located on ground or satellites. ground-based research implies systematic collection a network of receivers. Since 2000 "Pacific VLF network", conducted Japanese researchers, has operation. During 2008 receiver was developed Italian factory Elettronika (Palo del Colle, Bari). is equipment working and LF bands. It can monitor 10 frequencies...
Eumelanin-type biopolymers have attracted growing interest in the quest for soft bioinspired functional materials application organoelectronics. Recently, a metal-insulator-semiconductor device with good quality interface was produced by spin coating of commercial synthetic eumelanin-like material on dry plasma-modified silicon surface. As proof-of-concept step toward design and implementation next-generation eumelanin-inspired devices, we report herein an expedient chemical strategy to...
Current issues/challenges in the development of biocompatible eumelanin-based devices ranging from commercial eumelanins through 5,6-dihydroxyindole polymers to mussel-inspired polydopamine are presented.
Reproducible electrical contacts to organic molecules are created non-destructively by indirect electron beam evaporation of Pd onto molecular films on cooled substrates. In contrast, directly evaporated damage the seriously. Our conclusions based correlating trends in properties a series with systematically varying, exposed functional groups, behaviour Pd/molecule/GaAs junctions, where these same part junctions.
A jellified alginate based capsule serves as biocompatible and biodegradable electrolyte system to gate an organic field-effect transistor fabricated on a flexible substrate. Such allows operating thiophene polymer transistors below 0.5 V through electrical double layer formed across ion-permeable polymeric electrolyte. Moreover, biological macro-molecules such glucose-oxidase streptavidin can enter into the gating capsules that serve also delivery system. An enzymatic bio-reaction is shown...
Molecular control over charge transport across a metal/semiconductor interface persists even if there is only partial monolayer of polar molecules at the interface. This because long-range electrostatic effect dipole layer also affects semiconductor regions under film's pinholes. Thus, all types that show average order can be used.
Inspired by the powerful photosensitizing properties of red hair pigments pheomelanins, a photoresponsive cysteine‐containing variant adhesive biopolymer polydopamine (pDA) is developed via oxidative copolymerization dopamine (DA) and 5‐S‐cysteinyldopamine (CDA) in variable ratios. Chemical spectral analysis indicate presence benzothiazole/benzothiazine units akin to those pheomelanins. p(DA/CDA) copolymers display impedance similar biological materials marked photoimpedance response light...

Abstract. On 6 April 2009 a strong (Mw=6.3) earthquake occurred in the Abruzzo region (central Italy). Since 1996, intensity of CLT (f=189 kHz, Sicily, Italy), MCO (f=216 France) and CZE (f=270 Czech Republic) broadcast signals has been collected with ten minutes sampling rate by receiver operating place located about 13 km far from epicenter. During March 2009, old was substituted new one able to measure, minute rate, five VLF LF radiated transmitters different zones Europe. The mentioned...
The memory-like behavior of melanin biopolymer under electrical stimuli is shown through transport characterization performed on based metal insulator semiconductor structures silicon. presence a memory window and retention verified by capacitance-voltage read outs before after the application voltage pulses. Interestingly, these phenomena occur without metallic nanoclusters enclosed in matrix. Charge trapping considered main mechanism responsible for character. inability to erase has been...
Blood is a fluid connective tissue of human body, where it plays vital functions for the nutrition, defense and well-being organism. When circulating in peripheral districts, exposed to some physical stresses coming from outside as electromagnetic fields (EMFs) which can cross skin. Such may interact with biomolecules possibly inducing non thermal-mediated biological effects at cellular level. In this study, occurrence biochemical/biological modifications blood lympho-monocytes reverberation...
Abstract A dipole‐layer approach is adapted to describe the electrostatic potential and electronic transport through metal/semiconductor junctions with a discontinuous monolayer of polar molecules at interface. The effective barrier height those junctions, which have small pinholes, embedded in molecular layer, introduces negative {positive} dipole (i.e., whose pole one that closest semiconductor surface) on an n‐type {p‐type} semiconductor, often “tunable” by magnitude density dipoles. If...
