摘要
通过Te熔剂方法生长出〈331〉晶向的ZnTe体单晶, 利用X射线衍射和红外透射显微技术对材料进行了测试.在钛-宝石激光器的泵浦下, 利用〈331〉晶向的ZnTe晶体辐射-探测到太赫兹波, 激发频谱可达5 THz左右.〈331〉晶向的ZnTe晶体表现出良好的太赫兹辐射性能.
Abstract
〈331〉 oriented ZnTe crystals are grown by Te-solution method and the crystals are investigated by X-ray diffraction (XRD) and infrared transmission microscope technique.The 〈331〉 oriented ZnTe crystals pumped by Ti:Sapphire laser,are emitted and detected THz width about 5 THz. The〈331〉 oriented ZnTe crystals grown by Te-solution method, exhibit good property of THz radiation.
