Impact of device resistances in the performance of graphene-based terahertz photodetectors

引用

Frontiers of Optoelectronics 2024年第2期 89-99页

作者： óscar Castelló sofía M.López Baptista Kenji Watanabe Takashi Taniguchi enrique Diez Jesús enrique Velázquez-Pérez Yahya M.Meziani José M.Caridad Juan A.Delgado-Notario Department of Applied Physics University of Salamanca Unidad de Excelencia en Luz y Materia Estructurada(LUMEs) University of Salamanca Research Center for Electronic and Optical Materials National Institute for Materials Science Research Center for Materials Nanoarchitectonics National Institute for Materials Science Nanotechnology Group USAL–Nanolab University of Salamanca

In recent years, graphene field-effect-transistors(GFETs) have demonstrated an outstanding potential for terahertz(THz) photodetection due to their fast response and high-sensitivity. such features are essential to enable emerging THz applications, including 6G wireless communications, quantum information, bioimaging and security. However, the overall performance of these photodetectors may be utterly compromised by the impact of internal resistances presented in the device, so-called access or parasitic resistances. In this work, we provide a detailed study of the influence of internal device resistances in the photoresponse of high-mobility dual-gate GFET detectors. such dual-gate architectures allow us to fine tune(decrease) the internal resistance of the device by an order of magnitude and consequently demonstrate an improved responsivity and noise-equivalent-power values of the photodetector, respectively. Our results can be well understood by a series resistance model, as shown by the excellent agreement found between the experimental data and theoretical calculations. These findings are therefore relevant to understand and improve the overall performance of existing high-mobility graphene photodetectors.

Angiotensin II (Ang II) is the main mediator of the Renin-Angiotensin-system acting on ATsub>1sub> and other AT receptors. It is regarded as a pleiotropic agent that induces many actions, including functioning as a growth factor, and as a contractile hormone, among others. The aim of this work was to examine the impact of Ang II on the expression and function of αsub>1sub>-adrenergic receptors (αsub>1sub>-ARs) in cultured rat aorta, and aorta-derived smooth muscle cells. Isolated Wistar rat aorta was incubated for 24 h in DMEM at 37˚C, then subjected to isometric tension and to the action of added norepinephrine, in concentration-response curves. Ang II was added (1 × 10sup>−5sup> M), and in some experiments, 5-Methylurapidil (αsub>1Asub>-AR antagonist), AH11110A (αsub>1Bsub>-AR antagonist), or BMY-7378 (αsub>1Dsub>-AR antagonist), were used to identify the αsub>1sub>-AR involved in the response. Desensitization of the contractile response to norepinephrine was observed due to incubation time, and by the Ang II action. αsub>1Dsub>-AR was protected from desensitization by BMY-7378;while Rs-100329 and prazosin partially mitigated desensitization. In another set of experiments, isolated aorta-derived smooth muscle cells were exposed to Ang II and αsub>1sub>-ARs proteins were evaluated. αsub>1Dsub>-AR increased at 30 and 60 min post Ang II exposure, the αsub>1Asub>-AR diminished from 1 to 4 h, while αsub>1Bsub>-AR remained unchanged over 24 h of Ang II exposure. Ang II induced an increase of αsub>1Dsub>-AR at short times, and BMY-7378 protected αsub>1Dsub>-AR from desensitization.
