Terahertz (THz) plasma oscillation in n+nn+ InGaAs vertical diodes is studied by using a numerical approach based on the hydrodynamic (HD) equations. The 1D HD model is coupled to 1D Poisson equation. We simulate the diode response to the…

An analysis of generated Terahertz (THz) current oscillations taking place in one dimensional n+nn+ InGaAs diodes due to an optical photoexcitation and due to a dc operating bias are presented at room temperature. These oscillations have…

We use a hydrodynamic model self-consistently coupled to a 1D Poisson solver to simulate the excitation by optical beating as well as by electrical perturbation of plasma waves in n+nn+ InGaAs diodes at room temperature. We calculate the…

Financial markets in Lebanon are constrained by government influence, Islamic financial principles, and some barriers to foreign participation. Productivity in the Lebanese financial sector ranks below its occidental counterpart in spite…

This article tackles the interest rates’ convergence issue within 27 European countries. In this context, a series of data related to the interest rates within the aforementioned countries was used in order to test the rates’ convergence…

The analysis of the γp→ηπ0p reaction has been performed using data from the GRAAL experiment. The total and differential cross sections and the beam asymmetry have been obtained from threshold up to 1.5 GeV of beam energy. The two…

Abstract The photoproduction of double on the neutron is studied in the beam energy range of 0.6 up to 1.5 GeV, using a liquid deuterium target. The cross section and the beam asymmetry are extracted and compared to those previously…

The photoproduction of the ω meson has been studied at GRAAL from threshold up to a photon energy of 1.5 GeV. The differential cross sections and beam asymmetries have been measured precisely at all angles. The total cross section is also…
