Abstract:
In the presence of warm negative ions, ion-acoustic small-amplitude monotonic double layers are theoretically investigated in a plasma consisting of warm positive ions, warm positrons, and two-temperature non-isothermal electrons under the variation of the trapping parameters of electrons, concentration of positrons, and mass ratios of heavier negative ions to lighter positive ions by the Sagdeev pseudopotential method. The corresponding double layer solutions are also discussed for the same variation. Consequently, ion-acoustic solitary waves and double layers have been observed in auroral an

Abstract:
AbstractThe large-amplitude ion-acoustic double layers in a collisionless plasma consisting of isothermal positrons, warm adiabatic ions and two-temperature distribution of electrons are investigated. Using the pseudo-potential approach, an energy-integral equation for the system has been derived which encompasses complete nonlinearity for the plasma system. The existence region of the double layers is analyzed numerically. It is found that for a selected set of physical parameters, the rarefactive double layer exists in the electron–positron–ion plasma. It is found that the existence regime o

Abstract:
Double layers with a non-linear wave structure have been investigated by the well-known Sagdeev pseudopotential method in a plasma consisting of warm positive ions, warm negative ions, warm positrons, and two-temperature non-isothermal and isothermal electrons. In this work, the profiles of double layers from Sagdeev potential functions and double layer solutions for small-amplitude double layers between two-temperature non-isothermal and twotemperature isothermal electron plasmas are studied under a variation of the concentrations of positrons (χ), stream velocities of positive (uio) and nega

Abstract:
The conditions for the existence of an ion-acoustic double layer in a plasma with warm ions and two distinct groups of hot electrons have been studied using the Sagdeev potential method. A comparison is made with the published results of Bharuthram and Shukla for cold ions and a two-temperature electron population. Numerical studies have been made to find out the effect of a finite ion temperature on the Mach number of the double layers.

Abstract:
AbstractNon-planar (cylindrical and spherical) double layers (DLs) in two-ion-temperature dusty plasma, whose constituents are inertial negative dust, ions with two distinctive temperatures, and Boltzmann electrons, are studied by employing the reductive perturbation method. The modified Gardner equation describing the nonlinear propagation of dust-acoustic (DA) waves is derived, and its non-planar double layer solutions are analyzed numerically. The parametric regimes for the existence of DA DLs, which are found to be associated with positive potential only, are obtained. The basic features o

The head-on collision between two-counter-propagating electron acoustic solitons and double layers (DLs) in an unmagnetized collisionless multi-species plasma consisting of inertial cold electron fluid and ( α, q)-distributed hot electrons and positrons has been analyzed with the stationary background of massive positive ions. For nonlinear analysis of colliding wave phenomena, the coupled Korteweg–de Vries equation (KdVE), modified KdVE (mKdVE), and standard Gardner equation have been derived by adopting the extended Poincaré–Lighthill–Kuo technique.

Moreover, the sub-micron proton layer coated on the cone-shaped substrate makes the total proton beam experience the same accelerating field, thus the monochromaticity is maintai

Abstract:
The double-layer a-IGZO thin film transistors (DL-TFTs) using a quantum well channel and a top barrier can improve not only the electrical properties and the positive bias temperature instability as compared to the single-layer TFT (SL-TFTs) [1][2] but also the negative bias illumination stress (NBIS). In this work, DL-TFTs have less negative VT shifts than that of SL-TFTs under NBIS. Moreover, the negative VT shift of DL-TFTs decreases with increasing top barrier thickness due to the energy barrier formed by the valence band discontinuity at the interface between the channel layer and the top
