통과Te용제방법생장출<110>정향적ZnTe단정,이용X사선연사(XRD)급랍만광보대해재료진행료측시.상세연구료태혁자시역광보계통중해ZnTe단정작위격발화탐측정체적복사화탐측특성.결과표명재태-보석격광기적빙포하,Te용제방법생장적<110>정향적ZnTe정체표현출량호적THz복사성능,실온하격발빈보가체3THz이상.
<110> oriented ZnTe crystals were grown by Te-solvent method and tested by X-ray diffraction (XRD) and Raman scattering measurements. THz generation and detection characteristics of the Te-solvent-grown ZnTe electro-optic crystals were studied in detail in Terahertz-time domain spectroscopy. Our results show that the <110>-oriented ZnTe crystals can emit high signal noise ratio THz signal pumped by Ti: sapphire laser, and the THz pulse's width is over 3 THz at the room temperature.
