In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which  is integer and constant and k is wave vector). The longitudinal ...

Background: There is a great concern for the possible adverse effects of cell phones and noise waves and it looks these wave effects on the individuals’ health. Thus, the present study was conducted to examine the effect of cell phone waves, severity noise, and simultaneous effect of cell phone waves and severity noise on sperm motility and sexual hormones in adult male rats. Materials and Meth...

The propagation of arbitrary amplitude dust ion acoustic waves (DIAWs) in a magnetized collisional dusty plasma including hot electrons, with kappa velocity distribution for electrons, warm ions and dust particles has been studied. In the presence of immobile massive dust particulates, DIAWs have been investigated through the Sagdeev pseudo-potential method. It is demonstrated that the amplitud...

A nonlinear beat-wave regime of plasma wave excitation is considered. Two beat-wave drivers are considered: intensity-modulated laser pulse and density-modulated (microbunched) electron beam. It is shown that a long beat-wave pulse can excite strong plasma waves in its wake even when the beat-wave frequency is detuned from the electron plasma frequency. The wake is caused by the dynamic bistabi...

Modern microelectronics and nanoelectronics devices rely on the drift of electron localized at the interfaces between different materials, such silicon and silicon dioxide or gallium arsenide and aluminum gallium arsenide. Hence, the electron drift transit time in the active region of a device determines the maximum device speed. Instead of the electron drift, we propose to use the waves of the...
