  • Nt1310 Lab 7

    Fig.7, shows that, the insulator behavior of the PVA for pure PVA. But, with increasing the time of reaction there is an improvement in the electrical conductivity of the PVA-Ag nanocomposite films. Fig.7 shows that, the (I–V) characteristic of the samples, and the inset of Fig. 7 shows the relation between the conductivity and time of reaction. Then, the dc conductivity was calculated at the (voltage = 10 V) using the relation. (S/cm) Where (d) is the sample thickness, (A) is the area of the electrode and (R) is the sample resistance. The inset of Fig. shows that, it is clear that the conductivity increases with increasing the time of reaction. This can be illustrated on the basis of the charge transfer complexes (CTCs) formation inside the PVA chain network after AgNO3 doping PVA. It is known that, the charge transfer complexes forms by Ag nanoparticles in semi-crystalline polymers and for this reason reduces barrier height between the trapping sites, which in turn gives a conducting path through the amorphous regions of the PVA matrix (scheme 2) leading to enhanced the conductivity [31]. This behavior is assumed to decrease the activation energy of the carrier and boost the mobility towards the electrode during polarization. This case, Ag nanoparticles occupy the free volume holes (amorphous phase) and fill the interstitial positions between the PVA chains in the amorphous phase and connected these chains to some bonds by a charge interchange process between the Ag…

  • Sibeam Group Interview Report

    Interviewer: Okay Chris, thanks. One of the things that I heard mostly about SiBEAM, and I only had a chance to meet one of the founders when you guys were still in the old office, right at the integration was being announced. It was very early on and the purpose of that was to just find out about what this Silicon Image culture and it quickly became apparent within Silicon Image, their siting culture, and so now we are fast forwarding two years, and now it is Silicon Image, in Lattice and…

  • Physics Of Q-Dots Lab Report

    Introduction Quantum dots (Q-Dots) is very small semiconductor particles that means it can be either conductors or resist electricity depending on the temperature and purity of the semiconductor. Q-dots range in size from 2-10 nm, so because of their small size, quantum mechanics governs the physics of the particles. The synthesis Q-Dots were first studied in 1982 by Efros and Ekimov, and then many developments have reported the synthesis of semiconductor nanoparticles.1 Q-Dots have unique…

  • Moore's Law Essay

    The next month of the upcoming International Technology Roadmap for semiconductors is no longer aimed at Moore 's Law, according to an article in the <>, the world 's best-known academic journal. 50 years of the myth of the chip industry has finally been broken. 50 years ago, Gordon Moore predicted the development of the chip industry: When the price is constant, the performance of silicon chips every 18-24 months will be doubled. In fact, all this is unavoidable, since 1990, the…

  • Atomic Electronic Chip

    scientists have reached a point where they cannot make it any smaller. However, to determine the practicality of this new discovery, one must look at three different criteria: quality, cost, and application. Does the quality of this new material compare to that of the current material (silicon)? Does the cost of production make it worthwhile? Does this have practical applications? These are the questions that need to be asked to determine if this product is worth investing in. The first…

  • Photocatalyst Analysis Of Tio2

    Since the water splitting reaction using semiconductor electrode reported by Fujishima et al. in 1972 [1], there is increasing interest in the development of metal oxide photocatalysts for environmentally friendly applications such as air purification [2], hydrogen production via water splitting [3] and the removal of organic molecules from water [4]. Recently, photocatalyst thin film has aroused growing interests instead of a powder type of photocatalyst. Photocatalyst film can be deposited…
