![]() ![]() 2a, the interfacial state due to the suspended bonds brings about a dramatic decrease in mobility 24. However, for bulk materials, as the thickness goes into the nanometre size, as shown in Fig. At advanced transistor nodes, the channel thickness also needs to be thin enough to maintain effective gate control at shorter channels. In today’s big data era, the increase in computing power is forcing the performance of the underlying transistors to continue to improve. Transistors drove the explosive development of electronic applications in the form of integrated circuits. Ultrathin nanosheets for high-performance transistors ![]() The progress and challenges from functional devices to specific fusion applications in systems are also discussed, focusing on 2D semiconductors in specific electronic systems to overcome problems that are difficult to solve with conventional materials. Next, we introduced the electronic functions enabled by the novel physical properties of 2D semiconductors, mainly including three parts: computing, memory, and sense. we first consider the progress of 2D semiconductors as ultra-thin nanosheet channels for a higher-performance transistor, covering channel optimization, contact characterization, and dielectric integration. In this article, the progress, opportunities, and challenges of 2D semiconductors to develop specific electronic applications from devices to systems are reviewed. Here we focus on 2D semiconductors as the role of the channel in transistor architectures for constructing specific electronic applications. 2D materials cover a large multidisciplinary range which have been extensively reviewed 10, 11, 20, 21, 22, 23. Overall, the extensive physical characteristics of 2D semiconductors can be mined for specific electrical functions and hold great promise for all-in-one systems (Fig. On this basis, 2D semiconductors can implement device structures and functions previously unattainable with other materials and many innovative electronic devices have been invented, such as ultrafast non-volatile flash 15, 16, reconfigurable logic 17, 18, and logic-in-memory 19. Secondly, the abundant band engineering and the atomically smooth and flexible interface provide an additional degree of freedom for the fusion of different electrical functions, easy to create more efficient and specific applications by heterogeneous integration 14. 2D semiconductors have remained ignorant until the first monolayer MoS 2 transistors were prepared 13, revealing ultra-high on/off ratios, superior mobility, and ultra-low off-state currents. First, 2D semiconductors with intact structures at nanoscale are beneficial to create high-performance low-power electronic devices 12. But functionally integrated systems place stringent requirements on the heterogeneous integration of the underlying materials 8.ĢD semiconductors, as a family of emerging semiconductor materials 9, exhibit unprecedented new properties 10 that promise to overcome the barriers of miniaturization and specific applications 11. From the top, systems in complex scenarios such as IoT, edge computing require diverse interactions in specific environments 6, placing increasing demands on the integrated systems for specialized processing applications 7. From the bottom up, channel materials of transistors will be harder to make practical improvements in the future if it continues to shrink in the way as previously adopted 4 since the short-channel effects cannot be better addressed 5. Nevertheless, there are facing two major challenges from device to system. The data-intensive applications like artificial intelligence that shapes our lives are highly dependent on computing capabilities 1, pushing the need for hybrid data processing and application-specific functions at the system level 2, 3. Finally, we discuss the specific applications of functionalized arrays aiming at problems that are difficult to solve with bulk materials, like the fusion of memory and computation and the all-in-one system. Then we examined 2D semiconductors for specific electronic functions including computing, memory and sense.
