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…

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…

S-shaped current-voltage characteristics of n+-i-n-n+ graphene field-effect transistors due the Coulomb drag of quasi-equilibrium electrons by ballistic electrons

V. Ryzhii, M. Ryzhii, V. Mitin +2

We demonstrate that the injection of the ballistic electrons into the two-dimensional electron plasma in lateral n-i-n-n graphene field-effect transistors (G-FET) might lea…

Theoretical analysis of injection driven thermal light emitters based on graphene encapsulated by hexagonal boron nitride

V Ryzhii, T Otsuji, M Ryzhii +5

We develop the device model for the proposed injection (electrically) driven thermal light emitters (IDLEs) based on the vertical Hexagonal Boron Nitride Layer/Graphene Layer/ Hexa…
