中文拼音 [xīndānjīngtǐ]
鋅單晶體
英文
zinc single crystal-
Cadmium zinc telluride ( cd1 - xznxte or czt ) single crystal is one of the three element compound semiconductor materials with great performances used for the detection of x - ray and gamma - ray at room temperature
碲鋅鎘（ cd _ （ 1 - x ） zn _ xte ，簡寫czt ）單晶體是一種性能優異的三元化合物半導體室溫核輻射探測器材料，具有閃鋅礦型的面心立方結構。Cd1 - xznxte single crystal with good crystallinity has been grown by the descending ampoule with rotation method - before this, high - purity cd1 - xznxte polycrystal materials have been synthesized from 6n gd zn te in the same ampoule. on the basis of this, we deeply explore method of detector fabrication. and we also studied the level and density of traps in detector. gold, indium and c have been deposited as electrodes on polished and chemically etched surfaces of samples with the sizes from 5 5 1 to 10 10 1. 5mm to compare different contact technologies. the behavior of detector ' s leakage current with temperature and leakage current with time were studied as well as th current - voltage characteristics to deduce the level and density of trap in detectors
我們利用熔體溫度振蕩法在石英安瓿中將6n的單質cd 、 zn 、 te合成多晶原料，用坩鍋旋轉下降法在同一安瓿中生長出尺寸為20 40mm的cd _ （ 1 - x ） zn _ xte晶體。在此基礎上對碲鋅鎘探測器的工藝進行了較深入的研究，製作了厚1 ? 1 . 5mm的探測器，測試了c 、 in 、 au等不同金屬的電極接觸性能，並在國內首次通過測試器件的i ? v 、 i ? t曲線、弛豫特性和電容特性對電阻率、陷阱能級、陷阱濃度進行了分析，同時測得的~ （ 241 ） am源的能譜。Fe - sem, edx, xrd, saed and hrtem indicated that the regular arrays nanorods were wurtzite single crystal gan and the nanorods were tapered from the base to their upper end, which compatible with the theoretical result
Fe - sem ， edx ， xrd ， saed和hrtem結果表明：規則排列的納米棒是具有六方晶系纖鋅礦結構的gan單晶體，並且從西北工業大學博士學位論文底部到頂部具有塔形形貌，這一現象與理論推導結果一致。
