Otto configuration for the TM and TE surface plasmon detection in doped graphene at terahertz frequencies
No full textA numerical study of the TE and TM surface plasmon detection in free standing doped graphene by use of the Attenuated Total Reflectance technique is presented. It is demonstrated for both polarizations that wave interference leads to the perfect absorption phenomenon. For graphene, doping levels as high as 0.8 eV and 1.2 eV have been used for calculations
Purcell effect at silver nanowires and nanorings
No full textThe spontaneous emission enhancement at metallic nanowires and nanoringsis studied and the results are compared with each other. The maximum of the Purcell factor over the broad range of principal and minor nanoring radii values is found and plotted as a function of the distance between the emitter and the nanoring for different mode numbers
Metal-nonmetal oscillations in doped blue phosphorene:a first-principles study
No full textBased on density functional theory(DFT), we have investigated systematically the geometry structure and electronic properties of non-metallic atom doped blue phosphorene, such as B-, C-, N-, O-, Al-, Si- and S-doped blue phosphorene systems
