Abstract

In our earlier paper [T. Tojo and K. Takeda, J. Phys. Soc. Jpn. 88, 094711 (2019)], we revisited the Rashba spin–orbit interaction (SOI) in holes confined in the silicon two-dimensional quantum well (Si 2D QW) system, and explored the modulation of the spin textures as well as the electronic structures of the heavy-mass holes (HHs), light-mass holes (LHs), and separate holes (SHs). The complexity of the spin textures of these HHs, LHs, and SHs is expected to generate complicated Larmor spin precession. We therefore study how the Rashba SOI coupling modulates the Larmor spin precession of these holes. HHs and LHs exhibit spin flips under weak 2D quantization, whereas strong quantization removes the LH spin flips. In contrast, SHs do not experience any spin flips, irrespective of the quantization strength.
