In this paper, we report the study of I-V characteristics for some metal work functions. The Schottky barrier structure is controlled by the metal work function using the MATLAB programming language. The study of the effect of metal work function proved its influence on device performance, and a significant dependence was observed between this parameter and the electrical parameters at room temperature. The temperature effect on the electrical characteristics of n-AlGaAs Schottky diodes has been...

As for DE Broglie’s hypothesis of matter waves, many experimental physi-cists have experimentally verified it by using cathode ray tube and proved that matter waves do exist, so there is a mysterious hypothesis of wave-particle duality. In this paper, according to the electric field force of electrons in the cathode ray tube and the continuity equation of electrons, Under assumptions such as inelastic approximation, it is proved that the wave-particle duality is actually the macroscopic motion o...

It has been demonstrated that dark matter (DM) can theoretically be completely explained by a natural effect of General Relativity (GR) without exotic matter, the Lense-Thirring effect that exists exclusively in GR and that would be due to the clusters of galaxies. In this study, we show that this explanation of DM leads to a modelization that can be interpreted as MOND-based theories. More concretely, we retrieve from GR the value of MOND parameter a 0~10 -8cm·s -...

This research seeks to understand the fundamental properties of matter, such as mass, charge, and spin, and how they interact with each other. By studying the behaviour of these particles in different environments, scientists can gain insight into the nature of the universe. This research also has implications for our understanding of dark matter and dark energy, which are believed to make up the most of the universe’s mass but remain largely mysterious. Additionally, this research may provide c...

The Tully-Fisher law M ∝ v α is an empirical relationship between the mass of a galaxy and its asymptotic rotation velocity. The purpose of this research is to demonstrate that this relation can be theoretically obtained in General Relativity (GR) with a particular solution of dark matter (DM) in very good agreement with the observations. Several years ago, it was demonstrated that DM can theoretically be completely explained by a natural effect of GR without exotic matter, ...

It has been demonstrated that dark matter can theoretically be completely explained by a natural effect of General Relativity (GR) without exotic matter or exotic correction as MOND, an effect that exists exclusively in GR and which is traditionally considered negligible. We give the values of this effect necessary to fully explain the dark matter component. In the framework of GR, this solution is mathematically as valid and legitimate as the hypothesis of an “ad hoc” addition of exotic materia...

We introduce the concept of equivalent electromagnetic (EEM) field, on the basis of which we describe the gravitational field (G-field). We determine this EEM field based on the principle of equivalence (PE), i.e. by direct application of PE in the field equations and in the equations of motion, by introducing the EEM field potential. In this way, we introduce the mathematical formalism of the electromagnetic (EM) field into the G-field equations. This procedure of describing the G-field has a l...

This paper proposes a physical solution to primordial inflation. It occurs by a scalar field with a slow-rolling period. It starts at the phase transition giving rise to the gravitational interaction at time ti ~ 10 -44 s, Planck time, and ends at time tf ~ 10 -42 s (or more exactly about 70 e-folds later). This scalar field is carried by a primordial particle of inert mass mp ~ 1...

In this article, it is shown that if a particle is at rest and has some harmonic oscillation, then a traveling particle with a constant speed corresponds to a De Broglie Wave. In 1924, De Broglie proposed that particles of matter exhibit wave like behavior, the expression for which became fundamental in the creation of wave mechanics (quantum mechanics). The main equation for this is the Schrödinger equation, which in the case of free motion of a particle becomes the expression for the De B...
