“…Here, q is the charge of electron, V is the voltage that is applied to the device, A is the device area, k is the Boltzmann's constant, T is absolute temperature, A* is the effective Richardson constant, n is the ideality factor and ϕ b is Schottky barrier [17][18][19][20][21][22]. The saturation current is determined by the interpolation of exponential slope of I at V = 0 and ϕ b is obtained from the extrapolation of I 0 in the semi log forward bias I -V characteristics.…”

Present work will mainly focus on one of the most important applications of single-walled carbon nanotubes (SWCNTs). In this work, the different electrical parameters that are associated with the charge injection process at the metal−organic contact of the organic device will be estimated and subsequently, the effect of SWCNTs on those parameters will be measured. As we all know that high charge carrier trapping and high Schottky barrier at the metal−organic contact significantly affect the charge flow at the junction of organic dye-based device. It is of paramount importance to reduce these parameters which hinder the charge flow in the organic device. SWCNTs are one of the most prominent materials which can improve this charge flow at the metal−organic contact. Our main aim will be to study the physics behind the improvement of these electrical parameters in the presence of SWCNTs which will allow the device to perform more efficiently.

In this paper, snail shell powder was used an adsorbent for safranine dye due to its low cost, high efficiency and high adsorption capacity. Experiments were conducted at a temperature of 298 K to find out the effect of pH, concentration, weight, ionic strength and equilibrium time. Also, the best conditions for the adsorption of Safranin dye were implemented at a weight of 0.0200 g of snail shell powder. The removal ratio was 96.09 % at a concentration of 9mg/L and 20 minutes as adsorption time at a temperature of 298 K. The objective of the study to analyze the equilibrium isotherms. The data collected from the experiments were analyzed by the three models of adsorption: Langmuir, Temkin, and Freundlich. The data were suitable for Freundlich isotherm. The calculated thermodynamic information of the process shows that the removal process occurs through an active exchange of random molecules.

In this paper, the effects of two different solvents on the Schottky barrier of ITO/ blend of methyl red dye—fullerene nanoparticles/Al - M electrode have been studied. We have taken chlorobenzene solvent and toluene solvent. Three different devices have been made by taking three different weight ratios of the dye—nanoparticles blend which is 1:1, 1:2, and 2:1. The estimation of the interfacial Schottky barrier at the junction of metal-organic dye is estimated using the device’s dark I—V plot. Interfacial Schottky barrier at the metal-organic junction is least for 2:1 weight ratio of dye - nanoparticle blend in chlorobenzene solvent but for toluene solvent, the Schottky barrier is least for 1:2 weight ratio of dye—nanoparticle blend. The lowering of barrier height at 2:1 and 1:2 ratios in Schottky barrier contacts prepared with chlorobenzene and toluene solvents can be attributed to the filling up of traps at the metal-organic layer interface. The Norde method is also used to check the consistency of the obtained value of the Schottky barrier measured from I—V plots. Reduction in Schottky barrier results in improved current injection process at the metal-organic interface.
