    Distinct temporal evolution of PILS distribution in congruent and near-stoichiometric LiNbO3:Fe crystals detected by in-situ dynamic angular spectra

    In this paper, congruent and near-stoichiometric LiNbO3:Fe (CLN:Fe and SLN:Fe) crystals are prepared through Czochralski and Vapour-transport-equilibration techniques, and the temporal evolution of the photoinduc...

    Application of Graphene in Coating Silk Fibril for Tunable Infrared Absorption

    Infrared radiation is a primary mechanism for heat exchange between the human body and the environment. In the framework of Mie scattering theory, we investigate the infrared absorption of a graphene-coated si...

    Exploring Direct to Indirect Bandgap Transition in Silicon Nanowires: Size Effect

    We have investigated the electronic band structure of [110] silicon nanowires (SiNWs) using first-principles calculations. We find that, in the ultrathin diameter regime, SiNWs have a direct bandgap, but the e...

    Study on the temperature dependence of the OH− absorption band in Hf-doped LiNbO3 crystals

    We study in this paper the temperature dependence of the OH− absorption band in LiNbO3 crystals with different Hf-do** concentrations. It is found that the shoulder at 3500 cm−1 appears in the do** level of 2...
