Material family of zinc-blende structure semiconductors (ZBSSs) is important for novel technique such as spintronics. A study of the ZBSS spin-splitting structure in momentum space is essential when seeking to understand the exotic properties of the material. The Dresselhaus field predominates in the bulk, but the Rashba field plays important roles in states near the surface. Here, we used circular dichroism in angle-resolved photoemission spectroscopy (CD-ARPES) to explore the spin-splitting structure of bulk ZBSS in momentum space. The observed structure was well-explained by a Dresselhaus field attributable to the lack of inversion symmetry in ZBSS crystals. We show that CD-ARPES usefully reveals spin-splitting in momentum space. CD-ARPES combined with hard x-ray incident-beam would be useful to investigate the spin-splitting structures of the interface states in the ZBSS heterostructure.

闪锌矿结构半导体 (ZBSS) 的材料家族对于自旋电子学等新技术很重要。在寻求理解材料的奇异特性时，研究动量空间中的 ZBSS 自旋分裂结构是必不可少的。德雷塞尔豪斯场占主导地位，但拉什巴场在接近地表的状态中起着重要作用。在这里，我们在角分辨光电子能谱 (CD-ARPES) 中使用圆二色性来探索动量空间中体 ZBSS 的自旋分裂结构。由于 ZBSS 晶体缺乏反演对称性，Dresselhaus 场很好地解释了观察到的结构。我们表明 CD-ARPES 有效地揭示了动量空间中的自旋分裂。
