Ihe kristal

Semiconductor THz kristal: kristal ZnTe (Zinc Telluride) nwere <110> nghazi na-eji maka ọgbọ THz site na nhazi nhazi ngwa anya.Ndozi anya bụ ọgbọ dị iche iche ugboro ugboro na mgbasa ozi nwere nnukwu ohere nke abụọ.N'ihi na femtosecond laser pulses nke nwere nnukwu bandwit ihe ugboro ugboro na-emekọ ihe ọnụ na ọdịiche ha na-emepụta bandwit site na 0 ruo ọtụtụ THz.Nchọpụta pulse nke THz na-apụta site na nchọpụta electro-optic ohere efu na kristal ZnTe ọzọ <110>.A na-agbasa pulse THz na ihe a na-ahụ anya site na kristal ZnTe.Ụkụ THz na-ebute birefringence na ZnTe kristal nke a na-agụpụta ya site na usu a na-ahụ anya n'ahịrị kwụ ọtọ.Mgbe pulse a na-ahụ anya na THz pulse nọ na kristal n'otu oge, a ga-atụgharị polarization a na-ahụ anya site na THz pulse.N'iji λ/4 na-efegharị efegharị na polarizer na-agbakọta ọnụ yana usoro fotodiodes ziri ezi, ọ ga-ekwe omume ịdepụta njupụta nke pulse nke THz site na nyochaa ntụgharị polarization pulse a na-ahụ anya mgbe kristal ZnTe na oge dị iche iche nke igbu oge n'ihe gbasara pulse THz.Ikike ịgụpụta ọkụ eletrik zuru oke, ma njupụta na igbu oge, bụ otu n'ime njirimara mara mma nke oge THz spectroscopy.A na-ejikwa ZnTe maka ngwa ngwa ngwa anya IR na ntinye oghere.
