【摘要】 文章报道了采用Si基复合衬底,利用液相外延方法成功进行中波碲镉汞薄膜生长的情况,并且采用X光双晶衍射、X光形貌、红外付立叶光谱仪等手段对碲镉汞薄膜进行了表征。Si基复合衬底碲镉汞外延膜晶体结构为单晶,并且它的双晶衍射半峰值接近国外同类产品的先进水平。更多还原

【Abstract】 In the article the good result of LPE MW(Hg_1-xCd_xTe) on silicon composite substrates is presented,The Hg_1-xCd_xTe epilayer was characterized with X-ray diffraction,X-ray topography and FTIR. The LPE MW(Hg_1-xCd_xTe) on silicon composite substrate is single crystal,and its FWHM is as low as that of the best result published before.更多还原
