   利用m - lec法可以消除單晶中的位錯(cuò)，降低缺陷密度，降低單晶中的雜質(zhì)含量，并能使雜質(zhì)在晶體中的分布均勻，得到晶體均勻性、純凈度都高的gaas單晶。
4. Compared to gan , which is one of the most successful wide - band semiconductor materials at present , zno is promising : high - quality zno with very low defect densities can be synthesized at much lower temperature than gan ; zno can emits light with shorter wavelength than blue light emission from gan ; zno has higher excitonic binding energy ( ~ 60mev for zno , 25mev for gan ) , which promises strong photoluminescence from bound excitonic emissions at room temperature ; meanwhile , homogeneous bulk zno is available
   和gan相比， zno薄膜具有生長溫度低，激子復(fù)合能高( zno ： 60mev ， gan ： 21 25mev ) ，受激輻射閾值較低，能量轉(zhuǎn)換效率很高等優(yōu)點(diǎn)。有可能實(shí)現(xiàn)室溫下較強(qiáng)的紫外受激發(fā)射，制備出性能較好的探測(cè)器、發(fā)光二極管和激光二極管等光電子器件。
5. With plating time going on , the nano - polycrystal gathering grows in two dimensions , and the new nano - polycrystal layer appears simultaneously on the formerly formed nano - polycrystal surface . because the boundary and defect densities in quenched and tempered 45 steel is higher than those in annealed steel , the nano - polycrystal gatherings formed at its surface at the beginning of electro - deposition are more concentrated , and then their size is smaller . the microstructure of the ni - p alloy coating has closed relation with its phosphorus content with the increase of phosphorus content , the microstructure of coating turns from nano - crystalline to the amorphous
   隨著施鍍時(shí)間的延長，納米晶聚晶體在橫向二維生長的同時(shí)，在納米晶聚晶體的表面上也進(jìn)行著三維方向的新的一層聚晶體的生長；在調(diào)質(zhì)態(tài)45鋼表面，由于其具有比較高的晶界和缺陷密度，因此在沉積初期，納米晶聚晶體的成核密度也較大，從而在二維方向聚晶體的尺度較小，鍍層沉積初期表現(xiàn)為致密細(xì)小的鱗片狀組織。
6. It's difficult to find defect density in a sentence. 用defect density造句挺難的
7. Zno is promising : high - quality zno with very low defect densities can be synthesized at much lower temperature ; zno can emits light with shorter wavelength than blue light emission from gan ; zno has higher excitonic binding energy promising strong photoluminescence from the bound excitonic emissions even at room temperature ; by alloying with mgo , tuning of the band gap while keeping the zno hexagonal structure can be achieved by forming mgxzn1 - xo . as we know , band gap tuning is important to produce efficient and lasting light emitting diodes ( led ) and other electronic devices
   利用mg _ xzn _ ( 1 - x ) o薄膜，可以在保持zno六方纖鋅礦( wurtzite )結(jié)構(gòu)的同時(shí)有效調(diào)節(jié)調(diào)節(jié)薄膜的禁帶寬度，制備出基于氧化鋅的量子阱、超晶格及相關(guān)的光電器件，如基于氧化鋅的紫外光探測(cè)器、紫外發(fā)光二極管和紫外激光二極管等光電子器件。
