THz EMISSION AND DETECTION OF ZnTe BULK CRYSTALS GROWN BY Te SOLVENT METHOD
|
Abstract:
<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.
