hexagonal crystal meaning in English
六方晶体
六方晶系
六角晶体
Examples
- A hexagonal crystal , one of the three known structures iron can take , is different from the cubic crystalline structures iron takes at the planet ' s surface
六边形的水晶,能够得到的熟知的三结构铁,不同于从地球表面获得的立方体水晶的结构铁。 - Zinc oxide ( zno ) is a wide band gap ( 3 . 4ev ) semiconductor with the hexagonal crystal structure ( wurtzite type ) . zno thin films with the c - axis orientation perpendicular to the substrate show excellent piezo - electrical properties and are widely used in piezo - electrical filed . and the dense anjd uniform surface of the films is required when zno thin films are used as integrated functional films
Zno属于六方晶系6mm点群，晶体在c轴垂直面上的电性和弹性都是对称的，因而c轴择优取向的多晶薄膜能够具有单晶那样的压电性和光电性质，而具有平整均匀的表面形貌则是zno薄膜作为一种集成功能薄膜应用性能的保证。 - The peak position of zao films prepared at low temperature shifts to the lower angle comparable to that of bulk zno due to the residual stress ; as - deposited at high temperature or post - annealed zao films was polycrystalline with the hexagonal crystal structure and had a strongly preferred orientation of c axis perpendicular to the substrate surface , the minimum resistivity and average transmittance to the visible light can be obtained
研究表明， al _ 2o _ 3的掺杂在3wt时为最佳； zao薄膜在低温下沉积时，由于薄膜内存在残余应力使衍射峰位置与体材相比向低角度方向移动。高温沉积的zao薄膜或经热处理后的薄膜具有c轴择优取向的六角纤锌矿多晶结构，晶粒垂直于衬底柱状生长，薄膜可得到最小的电阻率和较高的可见光透过率。
