Polyvinylidene fluoride (PVDF) is a modern polymer material used in wide variety of ways. Thanks to its excellent resistance chemical or thermal degradation and low reactivity, it finds use biology, chemistry, electronics as well. By enriching the with an easily accessible cheap variant graphite, possible affect ratio crystalline phases. A correlation between ratios phases different properties, like dielectric constant well piezo- triboelectric has been found, but relationship them highly...
Abstract The absorption coefficient plays an important role in studying and characterizing semiconducting materials. It is parameter to study the mechanism of photons within structure studied material. Thus, it helps several types charge carrier transport along with energy band its defects. In literature, a formula was reported precisely calculate from raw data transmittance reflectance electromagnetic radiation. However, has issues limiting validity literature. this paper, we provide more...
In field electron emission (FE) studies, to interpret current-voltage data and extract characterization parameters, we use smooth planar metal-like emitter (SPME) methodology a data-analysis plot. Three types exist: Millikan-Lauritsen (ML), Fowler-Nordheim (FN) Murphy-Good (MG) plots. SPME methodology, ML FN plots are slightly curved but MG plot is nearly straight. 1956 FE theory better physics than 1928 theory, so expect be more precise or Current-voltage often converted: measured voltage...
Abstract This study investigates the crucial process of cleaning cold field emission electron emitters and scanning tunnel microscopy (STM) probes, particularly focusing on tungsten tips. The cleanliness these tips is essential for maintaining optimal cathode properties, preventing impurities that can significantly affect process. Various methods, including macroetching, ammonia cleaning, hydrofluoric acid (HF) were explored compared by microscopy. macroetching method, involving a mixture...
Ultrafast electron microscopy aims for imaging transient phenomena occurring on nanoscale. One of its goals is to visualize localized optical and plasmonic modes generated by coherent excitation in the vicinity various types nanostructures. Such capability was enabled photon-induced near-field microscopy, which based spectral filtering electrons inelastically scattered due stimulated interaction with near-field. Here we report development ultrafast 4D scanning transmission allows us image...
This text deals with the topic of liability state for damages caused by unlawfully conducted misdemeanour proceedings. issue is not elaborated in literature often, therefore authors aim to analyse its selected aspects more detail. The prosecution an offence constitutes a criminal charge within meaning Article 6(1) ECHR and effectively on same level as prosecution. Where person charged either or misdemeanour, such proceedings have been unlawfully, i.e., resulted final conviction decision...
This paper presents polymer graphite (PG) as a novel material for the scanning tunneling microscopy (STM) probe. Conductive PG is relatively modern nanocomposite used micro-pencil refills containing polymer-based binding agent and flakes. Its high conductivity immunity against surface contamination, with low price, make it seem like highly suitable electrode manufacturing in general. For tip production, three methods were developed are further described paper. commercially available rods...
Cloud storage has seen an increasing rise in demand and diffusion. Consequently, the cloud market is also becoming increasingly commoditised market. That is, homogenous products are offered at equal prices, this offer makes it more difficult for providers to generate revenue differentiate themselves from their competitors. Therefore, vital precisely understand customer preferences so that these can be targeted with appropriate services. To examine preferences, we conduct a choice experiment...
In this paper, a new theory is presented to explain the effects of polymer-coated cathodes based on an experiment. Experimental data were obtained by measuring total emission current from tip electrochemically etched polymer graphite rod, which acts as disordered array cathodes. Based experimental results (mainly time-current characteristics at fixed voltage values), physical model including equivalent circuit in paper describe its quasi-harmonic behaviour periodic charging and discharging....
This paper investigates field emission behavior from the surface of a tip that was prepared polymer graphite nanocomposites subjected to electrochemical etching. The essence preparation is create membrane etchant over an electrode metal ring. rod acts here as anode and immerses into filled with alkali etchant. After etching process, cleaned analyzed by Raman spectroscopy, investigating chemical composition tip. topography information obtained using Scanning Electron Microscopy Field Emission...
This study seeks to explain the adoption of cloud storage services as a means personal archiving thereby focusing on users' service and system quality perceptions their drivers. The authors derive empirically validate model that incorporates service/system well behavioral factors usage. Finally, highlight important determinants system/service providers should pay attention in attempts increase marketshare.
Field electron emission theory and experiments include testing analyzing the measured current-voltage characteristics using so-called Fowler-Nordheim or Murphy-Good plots. Although plots are theoretically predicted to be slightly curved almost-exactly straight, still they provide same results when applying field-emission orthodoxy test practical experimental data, near extracting emitter characterization parameters. This study is compare analysis that will obtained two methods data from...
Abstract This study compares different types of scanning probe microscopy (SPM) probes according to the function surface layer at tip apex. Three main SPM were analyzed: tunneling (STM) tungsten probes, conductive atomic force (AFM) and non-conductive AFM probes. The STM coated with a graphite simulate effects carbonization. tested specifically NenoProbe (platinum-coated tip) Akiyama gold. gold coating is intended improve conductivity help achieve homogeneous, oxidation-resistant surface....
