| 中文摘要 | We present the optical study of the ruthenate La4Ru2O10, which undergoes a semiconductor - semiconductor transition at 160 K. Two Ru-Ru interband transition peaks can be found in its HT phase. When temperature decreases across the transition, a transfer of spectral weight from low to high energy occurs. The peak which is located at lower energy in the HT phase is strongly suppressed below 160 K. Based on the analysis of structural distortions associated with this transition, we show that the spectral changes can be well understood by considering energetically reasonable orbital-selective occupancies of Ru t(2g) electrons. This proposed order of orbital energies offers specific insights into the HT insulating behavior, while the LT picture supports the current picture of a spin-singlet ground state. |
