Application of Two-Dimensional Semiconductor In Transistor

Two-dimensional semiconductor materials are a class of thin film materials with atomic thickness and unique electronic structure. They have important application prospects in semiconductor technology, especially in field effect transistors (FETs). This paper reviews the properties, applications, and challenges of two-dimensional semiconductor materials and their potential in different types of FETs. This paper introduces the representative members of two-dimensional semiconductor materials, including graphene, transition metal chalcogenides (TMDs) and black phosphorus, as well as their synthesis methods and bandgap regulation strategies. The paper then analyzes the applications and advantages of 2D semiconductor materials in digital, optoelectronic, pressure-sensitive, and brain-like FETs and their broad uses in electronic, optoelectronic, sensing, and energy storage devices. Finally, the main challenges facing 2D semiconductor materials in FETs are discussed, including material quality, contact resistance, process compatibility and environmental stability, and future research directions and prospects.
