Researchers at the University of Warwick and the University of Washington in the United States have developed a technique to visualize the electronic structure in microelectronic devices for the first time, which opens the door for the manufacture of two-dimensional semiconductors and highly coordinated high-performance microelectronic devices. The electronic structure of a material describes the behavior of electrons within the material, thereby reflecting the nature of the current flowing through the material. This behavior changes with the magnitude of the voltage applied to the material, and the electronic structure that changes with the voltage determines the efficiency of the microelectronic circuit. Changes in the electronic structure of the operating device are the basis of all modern electronic products, but so far, there is no way to directly see the specifics of these changes to help people understand how they affect electronic behavior. In order to visually observe and study the behavior of electrons in microelectronic devices and optimize the functions of microelectronic devices, researchers have developed a new technology that can be used to manipulate microelectronic devices made of so-called two-dimensional materials with only atomic thickness At the time, measure the energy and momentum of the electron; then use this information to visually express the photoelectric properties of the material. The technology uses angle-resolved optical emission spectroscopy (ARPES) to "excite" electrons in selected materials. By focusing a beam of ultraviolet or X-rays on a specific area of ​​atoms, the excited electrons will be hit from the atoms Out. Then, the researchers can measure the energy and direction of the electrons to calculate the energy and momentum they have in the material, which determines the electronic structure of the material. It can then be compared with theoretical predictions, which are calculated based on the most advanced electronic structures. Researchers believe that this technology allows the electronic structure of microelectronic devices to be visualized, allowing people to obtain the information needed to design higher-performance components, thereby creating electronic components with higher efficiency and lower energy consumption. It also contributes to the development of two-dimensional semiconductors, which are regarded as potential components for next-generation electronic products and have a wide range of applications in flexible electronics, optoelectronics, and spintronics. The research results led by the experiment were published in the recently published "Nature" magazine.
