科学圆桌会·趣谈2025| 物理学家：这一年，我们破解了晶体生长的“魔法”

Core Viewpoint - The article discusses a groundbreaking method for crystal growth in condensed matter physics, which challenges traditional theories and offers new opportunities for optical crystal applications in technology [2][3][12]. Group 1: New Crystal Growth Method - The new method, inspired by the growth of bamboo shoots, allows for the direct "pushing" of crystal materials from the base, leading to rapid growth rates of up to 50 atomic layers per minute and thicknesses exceeding 100,000 layers [7][9]. - This innovative approach, termed "lattice mass transfer-interface growth," significantly reduces defects and impurities in the crystals, resulting in high-quality materials suitable for advanced applications [7][9]. Group 2: Applications and Implications - The newly developed "ultra-thin corner optical crystal" has the potential to enhance chip integration and computing power, with projections indicating a significant increase in transistor density on chips the size of a fingernail [12]. - The method has already produced nine types of high-quality two-dimensional crystals, which can be utilized in integrated circuits and optical-electrical control, paving the way for the development of ultra-thin optical chips [12]. Group 3: Future Directions - The research team aims to advance to shorter wavelengths, specifically in the extreme ultraviolet range, which is crucial for cutting-edge technologies like photolithography and material structure detection [13]. - The goal is to develop a compact, stable, and versatile high-performance solid-state extreme ultraviolet light source, which could drive advancements in extreme condition physics and related fields [13].
