【摘要】 利用垂直Bridgman法生长了HgInTe单晶体,并采用X射线衍射分析、FT-IR光谱分析对晶体的形态结构及红外透过性能进行了检测,结果表明所生长的晶体是高质量的单相完整单晶体,其在400~4000cm-1范围内的红外透过性能较好,达到50%~55%,晶体对红外光的吸收主要为晶格吸收和自由载流子吸收引起的。更多还原

【Abstract】 HgInTe single-crystal has been grown by vertical Bridgman method and was investigated by means of X-ray analysis and FT-IR.The results showed that the as-grown crystal was single-phase crystal with high quality.The infrared transmittance in the middle and far infrared region was about 50%～55%.The absorption of the crystal to the infrared light was mainly lattice absorption and free carriers absorption.更多还原
