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

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.

减数分裂特异性调控分子Moa1定位到着丝粒受到动粒蛋白CENP-C的调控,同时Moa1参与黏连蛋白Rec8介导的着丝粒区域姐妹染色单体的黏连。为了研究这些蛋白质之间的相互作用,本研究利用酵母双杂交实验(yeast two-hybrid assay)测定分析了Moa1和CENP-C、Rec8之间的相互作用,并通过在Moa1中定点突变鉴定了与CENP-C和Rec8相互作用所需的一些氨基酸残基。实验结果表明,Moa1和CENP-C的相互作用对于Moa1参与调节姐妹动粒的单极附着很重要。然而,双杂交实验中与Rec8相互作用所需的Moa1的S143和T150突变没有显示出Moa1或Rec8功能的显著缺陷。这表明氨基酸残基的突变可能不足以干扰体内Moa1和Rec8之间的相互作用,需要进一步的研究来确定Moa1和Rec8的相互作用域。本研究揭示了影响减数分裂同源染色体分离的Moa1氨基酸位点,为减数分裂的染色体分离机制提供更深入的理解。

福泽谕吉《劝学篇》首章与明治革命

以“天不造人上之人,亦不造人下之人”为开篇的福泽谕吉《劝学篇》首章(1872年)常被认为效仿美国十三州《独立宣言》,其内容在当时的日本颇具冲击性。然而,福泽所表达的是人(男性)生来没有差别,因为有无学问才有了贫富、贵贱之差,这与《独立宣言》的主张截然不同。其阐述不如说是一种儒学思想,甚而言之,在当时实行科举制度的中国,这仅仅是一种社会现实。但在以身份、地位世袭制为基石的德川日本,这对政治、社会体制而言确是一种危险的理念。不仅如此,特别是在十八世纪以降,虽然日本广为学习儒学,但能够学习的大多数人实际乃是富贵阶层,“劝学”理念反过来成为了他们巩固地位的理论工具。然而同时,这种理想与现实之间的距离使得有才能之人逐渐产生积怨与愤恨。所谓“明治维新”,其作为一场破坏世袭身份制度的革命,得以发生的一大原因,便是下级武士所不断积蓄的不满与愤怒。

妇女解放是包含男性在内的“人的解放”政治课题的一种特殊形态。资本主义条件下的男女不平等是资本主义阶级差别在妇女及其活动场域中的具体形式。割裂妇女解放斗争与工人解放运动的关系,将妇女解放曲解为针对男性的斗争,以及围绕职场与家庭之间的所谓经验化论争,均无法为妇女解放提供真正的理论指导。由于日本资本主义的特殊形态及具体展开的历史过程,20世纪日本妇女解放运动艰辛曲折,发展缓慢。虽然经由二战后日本经济结构重组和社会民主化进程的带动,大众化的妇女解放运动和相应法律制度得以快速发展,但妇女的生活实际与既有法律之间存在巨大距离,妇女权益保护更表现出局域化、碎片化局面。立足妇女与工人阶级的内在联系,统摄妇女权益内部差别,构筑新的妇女解放的法学理论,推进妇女权益的社会实质平等,是日本马克思主义法学必须承担的时代课题。
