中国基于同步辐射光源的ARPES线站简介

A short introduction to synchrotron radiation-based angleresolved photoemission spectroscopy endstations in China

角分辨光电子能谱(ARPES)凭借直接探测电子能量和动量的优势,在研究固体材料能带结构、费米面以及能隙等方面发挥着重要作用.近年来,通过追随国际领先水平,我国ARPES技术得到了飞速发展,其中与第一、二、三代同步辐射光源的结合更是帮助凝聚态物理和自旋电子学等研究方向实现了许多重大突破.本文从线站技术特点和主要成果两个角度简要介绍了目前中国主要的基于同步辐射ARPES光束线站:包括合肥光源角分辨光电子能谱线站,上海光源“梦之线”、BL03U、BL07U-Nano ARPES和BL07U-自旋分辨ARPES线站,同时还对基于未来合肥先进光源的新ARPES线站进行了展望.这些实验站将在新型量子材料探索与调控、微纳原型器件的研发等方面提供关键且不可替代的技术支撑.

Angle-resolved photoemission spectroscopy(ARPES)plays an important role in studying the band structure,Fermi surface,and gap of solid materials because of its advantages in directly detecting electron energy and momentum.In recent years,China's ARPES technology has advanced rapidly by following international standards.Collaboration with the first-,second-,and third-generation synchrotron radiation facilities has contributed to many major breakthroughs in condensed matter physics and spintronics.This paper briefly introduces the main ARPES beamline stations based on synchrotron radiation in China from the technical characteristics and main achievements,including the Hefei Light Source ARPES beamline station,the Shanghai Synchrotron Radiation Facility“Dream Line",BL03U,BLO7U-Nano ARPES,and BLO7U-spin-resolved ARPES beamline stations.Simultaneously,it anticipates the future ARPES beamline stations based on the Hefei Advanced Light Source.These experimental stations will provide critical and irreplaceable technical support in the exploration and control of new quantum materials,the research of micro and nanoscale prototype devices,and so on.
