Bulk photoemission from metal films and nanoparticles

Autor: Alexander V. Uskov, Igor E. Protsenko, M E Guzhva, Viktoriia E. Babicheva, R. Sh. Ikhsanov

Publikováno v: Quantum Electronics. 45:50-58

Internal emission of photoelectrons from metal films and nanoparticles (nanowires and nanospheres) into a semiconductor matrix is studied theoretically by taking into account the jump of the effective electron mass at the metal – semiconductor inte

Publikováno v: Ferroelectrics. 469:43-49

Temperature dependences of the dielectric permittivity and thermal treatment effect have been studied for (1−x)SrTiO3-(x)KTaO3 and (1−x)SrTiO3-(x)KNbO3 (0 ≤ x ≤ 0.2) solid solutions. For low concentrations x, strong dielectric relaxation was

Dependence of the Electron Photoemission from Metallic Nanoparticles on Their Size

Autor: Renat Sh. Ikhsanov, M. E. Guzhva, Igor E. Protsenko, Alexander V. Uskov

Publikováno v: Journal of Russian Laser Research. 35:501-508

We study the spectral dependence of the internal quantum efficiency of electron photoemission on the size of spherical metallic nanoparticles embedded in a semiconductor matrix and discuss theoretically the volume mechanism of the photoeffect. We tak
