In this paper we propose a semantics for dyadic deontic logic with an explicit preference ordering between worlds, representing diierent degrees of ideality. We argue that this ideality ordering can be used in two ways to evaluate formulas , which we call ordering and minimizing. Ordering uses all preference relations between relevant worlds, whereas minimizing uses the most preferred worlds on...

Abstract The fabrication of diodes using organic semiconductors as active materials has gained wide interest, and undergone significant progress in the past few decades. A naphthalimide-indole derivative (BNIA) was synthesized through bromination acenaphthene, subsequent oxidation, finally imidation with indole-3-acetic anhydride. molecular structure characterized NMR IR spectroscopy. BNIA disp...

Zinc thin films deposited on (n-type)silicon at 510o C with oxidation times (10,20,30,35) sec have been oxidized. by thermal diffusion method using heater instead of conventional furnace .It is found that we can get zinc oxide outoxegen and closed farneces rapidly. The electrical properties in dark show the detector shottky diode, best time to obtain 35 sec, ideality factor 3.3 a work function ...

Abstract In this work, we measured the I-V characteristics of silica nanoparticles (SNPs) extracted from Pleurosira laevis diatom and deposited on top a p-type Si(111) wafer. The electric response SNPs-based diode is found to be more sensitive thermal optical power than fresh frustules-based by about 3 5 times, respectively. Moreover, chemically processed SNPs exhibit better parameters, i.e. fo...

Today's circuit technology requires low-power transistors and diodes to extend Moore's law. While research has been focused on reducing power consumption of transistors, have not widely studied. Here, we report a low-power, thus steep-slope Schottky diode, with “cold metal” source. The barrier between metal electrode bulk MoS 2 enabled the diode behavior, IV curve originated from change in dens...

using solvent evaporating and atomic emission spectrophotometric methods, the solubility of li2co3 in waterat 25°c was determined. comparing the value of thermodynamic solubility product constant, ksp(th),(ksp(tn) = exp(—ag.ss/rt)) of the mentioned salt to the value which is obtained from the observed solubility,shnoll-1 , and activity coefficients, f+ and f, which are estimated upon the extend...

Graphene (Gr) is of great interest in the development new electronic, photonic, and composite materials. The physical properties Gr can vary depending on number layers, this unique property makes it a potential material for different electronic applications. In study, few-layer graphene (FLG) film was spin-coated onto InP semiconductor surface FLG/n-InP Schottky contact produced. quality FLG na...
