Low-frequency Raman signature of Ag-intercalated few-layer MoS
Natalya Sheremetyeva, Drake Niedzielski, Damien Tristant +4
Density functional theory based calculations and experimental analysis on a limited number of real samples are performed to study how the presence of silver intercalated in the van…
Ballistic injection terahertz plasma instability in graphene n+-i-n-n+ field-effect transistors and lateral diodes
V. Ryzhii, M. Ryzhii, A. Satou +3
We analyze the operation of the graphene n+-i-n-n+ field-effect transistors (GFETs) and lateral diodes (GLDs) with the injection of ballistic electrons into the n-region. The momen…
Giant Inverse Faraday Effect in Plasmonic Crystal Ring
G. R. Aizin, J. Mikalopas, M. Shur
Circularly polarized electromagnetic wave impinging on a conducting ring generates a circulating DC plasmonic current resulting in an Inverse Faraday Effect in nanorings. We show t…
Effect of Coulomb carrier drag and terahertz plasma instability in p+-p-i-n-n+ graphene tunneling transistor structures
V. Ryzhii, M. Ryzhii, A. Satou +3
We evaluate the influence of the Coulomb drag of the electrons and holes in the gated n- and p-regions by the ballistic electrons and holes generated in the depleted i-region due t…
Bilayer twisting as a mean to isolate connected flat bands in a Kagome lattice through Wigner crystallization
Jing Wu, Yuee Xie, Mingxing Chen +4
The physics of flat band is novel and rich but difficult to access. In this regard, recently twisting of bilayer van der Waals (vdW)-bounded two-dimensional (2D) materials has attr…
Coulomb electron drag mechanism of terahertz plasma instability in n+-i-n-n+ graphene FETs with ballistic injection
V. Ryzhii, M. Ryzhii, V. Mitin +2
We predict the self-excitation of terahertz (THz) oscillations due to the plasma instability in the lateral n+-i-n-n+$ graphene field-effect transistors (G-FET). The instability is…
