Surface metallization from ab initio theory and subwavelength coupling via surface plasmon polaritons in Cu-doped lithium niobate/tantalate owing to charge accumulation

Multi-Physical Analysis and Optimization in Integrated Lithium Niobate Modulator Using Micro-Structured Electrodes

“…To address this, we intend to conduct more comprehensive research in the future by reconfiguring our model and performing more refined analyses. Furthermore, we hope to explore the influence of additional techniques, such as the application of surface metallization on LN [20], in order to achieve more precise and comprehensive research outcomes.…”

Boron structure evolution in magnetic Cr2O3 thin films

“…Rare earth dopants on the substitutional site of 2D transition metal chalcogenides can greatly modulate the optical properties [4][5][6][7]. Substituting the host cation in the metal oxides always greatly promotes the surface plasmon [8][9][10][11]. Doping on the interstitial sites in semiconductors was reported to substantially modify the electronic and band structures for energy applications [12,13].…”

Dramatic n-Type Doping of Monolayer Graphene with Ferroelectric LiNbO3 Crystals and Bilayer Two-Dimensional Electron Gases

“…Especially, the interface polar discontinuity can cause surface atom reconstruction and charge carrier transfer to compensate the SP. − The depolarization process can accumulate 2DEGs in the nanometric scale on the surface, which is able to support visible surface plasmon polaritons (SPPs) . Recently, it has been proven theoretically and experimentally that bare LN or ITO-coated LN has a surface-metallized layer (2DEG in essence) to support visible SPPs, which leads to extremely intense energy coupling between laser beams and SPPs. − In fact, the super strong SP field can exert on the covering layer or other adsorbates. Based on this influence, an all-optical modulator was conceived and simulated lately, yet more related theoretical and experimental works are needed.…”
