Integrated Graphene-Based Optoelectronic Devices Used for Ultrafast Optical-THz Photodetectors, Modulators and Emitters

Abstract

We carried out numerical simulations on multilayer plasmon excitations by resonant energy transfer. A formal derivation of the transfer rate from the plasmons to the Wannier excitons was performed. We stimulated fluorescence and compared our results with the conventional organic/inorganic hybrid organic light-emitting diode (OLEDs). We formulated electron energy loss spectroscopy (EELS) for multilayer epitaxial grapheme. Our derivation of the general angles-resolved EELS spectra for transmission and reflection is based on the prescribed electron trajectory. In particular, we were interested in application of the theory to various multi-layer electron gas (MLEG) configurations, i.e., epitaxial vs. exfoliated graphene. We did a comparison with the available experimental data to see the effect of the gap between the valence and conduction bands.
