| 摘 要： | 掺杂半导体中的载流子吸收在THz波段非常明显，其相互作用研究是研制THz通信中的关键器件之一的基础。采用氟化氪（KrF）脉冲准分子激光烧蚀沉积（PLD）技术，制备了Ni掺杂BaTiO3/SrTiO3多层膜。基于辐射频率为3.09 THz、脉冲功率为10 mW量级的THz 量子级联激光器(QCL)光源研究了太赫兹波在Ni掺杂BaTiO3/SrTiO3多层膜中的传输，发现损耗主要是Ni颗粒的非共振吸收导致。

| Abstract: | The carrier absorption of the doped semiconductor materials is evident in terahertz (THz). The reciprocity study is the basis for preparing the key apparatus in the THz communications. Using a pulsed KrF excimer laser ablation (PLD) technique, the Ni-doped BaTiO3/SrTiO3 multilayer film has been prepared. Based on 3.09 THz quantum cascade laser (QCL) with the peak optical power about 10 mW, the transition of THz waves in the Ni-doped BaTiO3/SrTiO3 multilayer films is studied. It is found that the main loss may be due to the nonresonant absorption of Ni particles. |
