硅材料作为电子产业的基础,数十年来一直是信息经济发展的实质动力。随着电子器件尺寸的缩小和处理速度的加快,晶体管尺寸已经迫近极限,探索新的物理机制与结构来缩小硅晶体管的线宽也只能延续5～10年,找到替代材料,或开发纳米材料是当前电子技术进一步发展的核心问题。氮化物半导体材料最早是在光学领域 Silicon material, the basis for the electronics industry, has been a substantial driver of the development of the information economy for decades. As the size of electronic devices shrinks and processing speed increases, the transistor size is approaching the limit. Exploring new physical mechanisms and structures to reduce the line width of silicon transistors can only last 5-10 years, finding alternative materials or developing nanomaterials Is the core issue of the further development of electronic technology. Nitride semiconductor materials were first in the field of optics
