Solvent-Directed Femtosecond Laser Ablation: Tuning Phase and Defect Engineering in Hybrid CdPS3/CdS Nanostructures
Andrei Ushkov, Nadezhda Belozerova, Gleb Tikhonowski +8
The limited visible-light absorption of wide-bandgap van der Waals crystals fundamentally restricts their utility in solar energy conversion. Here, we report a surfactant-free, sol…
Modulation characteristics of uncooled graphene photodetectors
V. Ryzhii, M. Ryzhii, T. Otsuji +3
We analyze the modulation characteristics of the uncooled terahertz (THz) and infrared (IR) detectors using the variation of the density and effective temperature of the two-dimens…
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…
Negative terahertz conductivity at vertical carrier injection in a black-Arsenic-Phosphorus-Graphene heterostructure integrated with a light-emitting diode
Victor Ryzhii, Maxim Ryzhii, Taiichi Otsuji +4
We propose and analyze the heterostructure comprising a black-arsenic-phosphorus layer (b-AsPL) and a graphene layer (GL) integrated with a light-emitting diode (LED).…
Negative photoconductivity and hot-carrier bolometric detection of terahertz radiation in graphene-phosphorene hybrid structures
V. Ryzhii, M. Ryzhii, D. S. Ponomarev +4
We consider the effect of terahertz (THz) radiation on the conductivity of the ungated and gated graphene (G)-phosphorene (P) hybrid structures and propose and evaluated the hot-ca…
Real-space-transfer mechanism of negative differential conductivity in gated graphene-phosphorene hybrid structures: Phenomenological heating model
V. Ryzhii, M. Ryzhii, D. Svintsov +6
We analyze the nonlinear carrier transport in the gated graphene-phosphorene (G-P) hybrid structures - the G-P field-effect transistors (G-P-FETs) using a phenomenological model. T…
