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.

耐药菌的不断出现已成为人类和动物健康的严重威胁.开发高效、低耐药的新型非抗生素治疗药物是对抗耐药菌的有效策略.在这里,我们设计了一种新型的复合结构,即中空金属有机框架(MOF)包裹金纳米棒并负载铂纳米颗粒(Au NR@H-ZIF-8@Pt)用以对抗耐药细菌.Au NR@H-ZIF-8@Pt复合结构具有双重作用:(1)在近红外光照射下表现出优异的光热转换效率,从而实现基于光热效应的抗菌作用;(2)表现出高效的过氧化物酶样活性,通过原位产生的活性氧(ROS)有效杀灭细菌.结合光热和催化作用进行体外抗菌实验, Au NR@H-ZIF-8@Pt表现出高效、快速、广谱的抗菌活性(对铜绿假单胞菌和金黄色葡萄球菌的灭菌效果分别高达99.7%和98.3%).此外,体内实验进一步证明了该材料在促进细菌感染创面愈合方面的优势.本研究不仅有利于新型生物纳米材料的设计,也为对抗耐药菌提供了新思路.

Anti-parity-time symmetry hidden in a damping linear resonator

Science China(Physics,Mechanics & Astronomy) 2023年第10期66卷 22-32页

Phase transition from the over-damping to under-damping states is a ubiquitous phenomenon in physical systems. However, what kind of symmetry is broken associated with this phase transition remains unclear. Here, we discover that this phase transition is determined by an anti-parity-time(anti-PT) symmetry hidden in a single damping linear resonator, which is significantly different from the conventional anti-PT-symmetric systems with two or more modes. We show that the breaking of the anti-PT symmetry yields the phase transition from the over-damping to under-damping states, with an exceptional point(EP) corresponding to the critical-damping state. Moreover, we propose an optomechanical scheme to show this anti-PT symmetry breaking by using the optical spring effect in a quadratic optomechanical system. We also suggest an optomechanical sensor with the sensitivity enhanced significantly around the EPs for the anti-PT symmetry breaking. Our work unveils the anti-PT symmetry hidden in damping oscillations and hence opens up new possibilities for exploiting wide anti-PT symmetry applications in single damping linear resonators.
