Over the past 70 years, the semiconductor industry has undergone transformative changes,largely driven by the miniaturization of devices and the integration of innovative structures and materials. Two-dimensional(2D) materials like transition metal dichalcogenides(TMDs) and graphene are pivotal in overcoming the limitations of silicon-based technologies, offering innovative approaches in transistor design and functionality, enabling atomic-thin channel transistors and monolithic 3D integration. We review the important progress in the application of 2D materials in future information technology, focusing in particular on microelectronics and optoelectronics. We comprehensively summarize the key advancements across material production, characterization metrology, electronic devices, optoelectronic devices, and heterogeneous integration on silicon. A strategic roadmap and key challenges for the transition of 2D materials from basic research to industrial development are outlined. To facilitate such a transition, key technologies and tools dedicated to 2D materials must be developed to meet industrial standards, and the employment of AI in material growth, characterizations, and circuit design will be essential. It is time for academia to actively engage with industry to drive the next 10 years of 2D material research.

The etching process of high-performance recessed-gate In Al N/Ga N high-electron mobility transistors(HEMTs) has been actively researched. This paper proposes a post-etching self-limited surface restoration method that effectively suppresses the etching damage, enhancing the transport properties of recessed-gate In Al N/Ga N HEMTs. We fabricated planar-gate devices, inductively coupled plasma(ICP)-etched devices, and post-etching-treated(PET) devices. The damage caused by the ICP etching process severely deteriorated the transport properties of the devices. However, the post-etching process effectively inhibited the etching damage and improved the device transport properties. Through temperature-dependent tests and a simulation, the change in the peak transconductance was compared among different devices. The temperature-dependent optical phonon scattering and impurity-dependent remote charge scattering mechanisms were analyzed. The results confirmed that the etching damage significantly affected the channel electron scattering mechanism. The field-effect mobility showed a linear relationship with temperature, and the optical phonon scattering model illustrated that the field-effect mobility decreased with increasing temperature. The etching damage caused a decrease in the field-effect mobility from 1075.5 to 699.1 cm~2/V·s,which increased the fitting error between this empirical line and the optical phonon scattering fitting curve from 0.086 to 0.948, similar to the remote charge scattering fitting curve. The combined error range is from 0.896 to 0.054.

随着油气勘探开发向非常规领域深入,压裂等储层改造措施的应用越来越广泛。为了深入认识储层特性,了解储层潜力,预测储层改造后敏感性特征变化,从而进行合理的储层保护措施,有必要开展储层岩心模拟改造后的敏感性实验,明确储层改造措施对储层敏感性特征的影响。基于钻井获取岩心,在薄片鉴定、X射线衍射、扫描电镜分析以及压汞测试实验等手段的基础上,开展不同压力、温度、流体化学性质等条件下的流动实验,以评估储层的敏感性特征。通过对比改造前后岩心敏感性实验结果的差异,分析储层改造措施对储层敏感性特征的影响。结果表明:①模拟储层改造后中侏罗统沙溪庙组8号砂体岩心出现网状裂缝,渗透率相比改造前平均提升167%。②改造之前的JQ地区沙溪庙组岩心具有中等偏弱速敏、强水敏、弱盐敏、弱碱敏、弱酸敏的特征;改造后,速敏、盐敏等敏感性特征没有改变,而水敏由强转弱,强水敏的样品比例由93%下降到17%。③综合分析改造后敏感性特征,改造后岩心的水敏程度较改造前下降,出现弱水敏和无水敏的结果,因此需要增加储层改造措施的影响范围,以此提升储层流体流动能力。

The field of silicon nanophotonics has attracted considerable attention in the past decade because of its unique advantages,including complementary metal–oxide–semiconductor（CMOS） compatibility and the ability to achieve an ultra-high integration density. In particular, silicon nanophotonic integrated devices for on-chip light manipulation have been developed successfully and have played very import roles in various applications. In this paper, we review the recent progress of silicon nanophotonic devices for on-chip light manipulation, including the static type and the dynamic type. Static onchip light manipulation focuses on polarization/mode manipulation, as well as light nanofocusing, while dynamic on-chip light manipulation focuses on optical modulation/switching. The challenges and prospects of high-performance silicon nanophotonic integrated devices for on-chip light manipulation are discussed.
