摘    要:以分析市场对显示器件的需求为基础,为了寻找适合场致发射的最佳材料,对金刚石粉的晶体结构、颗粒形貌和尺寸进行了分析,得知其微观形貌正好满足场致发射的理论要求.由于制备大面积纳米晶体金刚石薄膜材料的周期很长,且晶体金刚石的电阻率很大并很难掺入杂质,我们选用金刚石纳米粉和能够适合大面积、大批量生产的热粘工艺,从实验上研究并确定了金刚石与金属热粘工艺的可行性,为场致发射器件的研制提供了可靠的实验依据.

关 键 词:场致发射  金刚石粉  热粘接技术

Abstract:In order to search optimum material in field emission,the crystal phase,microstructure and size of diamond powder were analyzed with modern analysis instruments.The analyzed results have proved that diamond powders are nano crystalline with edges and corners,which just meet the theoretical demand of field emission.Because the period preparing large flake of nano crystalline diamond film is very long,together with that the resistivity of bulk crystal diamond,which is difficult to mix into impurity,is very high,we select nano crystalline diamond powder and thermal adhering technics between diamond and metals,which adapts to large area and batch production.Finally we have proved experimentally the thermal adhering technics between diamond and metals is feasible.
Keywords:Field emission  Diamond powder  Thermal  adhering technics
