Theoretical study of the surface waves in semi-bounded quantum collisional plasmas

Abstract: The propagation of surface waves on a semi-bounded quantum plasma is investigated taking into account the collisional effects. The quantum hydrodynamic model includes Bohm's quantum force, Fermi-Dirac statistical, and collisional corrections are used to derive the dispersion relation of these waves. It is shown that the collisions play a significant role on the decay of surface wave amplitude. Furthermore, the surface waves can be unstable in the presence of collisional effects. It is also indicated that the g… Show more

“…Thus, the typical quantum effects such as the exchangecorrelation, the quantum fluctuation due to the density correlation, and the degenerate pressure will play a significant role in the electronic components to be constructed in future. In the previous investigations (Ritchie, 1963;Kaw and McBride, 1970;Lazar et al, 2007;Mohamed, 2010;Misra, 2011;Zhu, 2015), the basic features of the surface waves in semi-bounded plasmas have been investigated under the influence of the quantum tunneling (Shahmansouri, 2015;Moradi, 2017), relativistic effects (Zhu et al, 2013), spin fermions (Andreev and Kuzmenkov, 2016), the collisional effects (Khorashadizadeh et al, 2012), exchange effects (Shahmansouri, 2015;Moradi, 2017;Shahmansouri and Mahmodi, 2017), as well as the external magnetic field (Mohamed, 2010).…”

“…The propagation of surface waves in plasmas and in conducting solids has been a topic o f important research over the last many years [1][2][3][4][5][6][7][8][9][10][11][12]. Surface Plasmon (SP) waves can be excited due to the collective oscillation of free electrons at the interface of plasmas of different densities or plasma -vacuum interface.…”

“…[21,22] Excitation of Transverse Magnetic (TM) surface waves in magnetized spin quantum plasmas was also studied by Mohamed, and he used an approximate method to obtain dispersion relation; therefore, the importance of the spin effect is not clearly shown in his results. [25,26] Those effects were found to facilitate the propagation of surface waves. [24] The effect of an external magnetic field and collision on the propagation of surface waves in quantum plasmas was studied in our previous works.…”
