Smartphones contain billions of tiny switches called transistors. These switches allow people to handle countless tasks other than making phone calls, such as sending text messages, navigating in the community, and taking selfies. They include a conductive channel whose conductivity can be changed by a gate terminal. The gate terminal is separated from the channel by a dielectric film with a thickness of only 5-6 atoms. According to Moore's Law, transistors have been miniaturized over the past 50 years. Moore's Law observes that the number of transistors on a chip approximately doubles every 18 months, and the cost is halved. But now, people are already facing the situation that the transistor cannot be further expanded. In the Applied Physics Letters of the American Institute of Physics (AIP), the researchers reviewed the development of negative capacitance field effect transistors (NC-FETs). NC-FETs are a new device concept. It shows that only a thin layer of ferroelectric material can be added to greatly improve the efficiency of traditional transistors. If put into use, the same chip can calculate more and require less frequent charging. In the above article, the researchers summarized the latest research results of NC-FETs, as well as the various experimental reports reported in the literature that need to be consistent and coherent. "NC-FETs were originally proposed by my colleague Supriyo Datta and graduate student Sayeef Salahuddin. He is now a professor at the University of California, Berkeley." Muhammad Ashraful Alam, a professor of electrical and computer engineering at Purdue University, said. From the beginning, Alam discovered that the concept of NC-FETs is very interesting. It not only solves the urgent problem of finding new electronic switches for the semiconductor industry, but also a generalized phase change device commonly known as "Landau switch". Conceptual framework. "Recently, when my colleague and co-author Professor Peide Ye started experimenting with these transistors, I had the opportunity to collaborate with him to explore the interesting characteristics of this device technology." Alam said, "Our article summarizes this topic. 'Theory-Experiment' view. "(Xu Xu) Dongguan Best Instrument Technology Co., Ltd , https://www.dgbestinstrument.com
