项目摘要
Objective and approach:The objective of this research is to synthesize well ordered self assembled arrays of rare earth sulfide nanowires. This will result in dense arrays of highly efficient field emitters that have low work function (~ 1 eV) and high melting point (~ 2000 C). They will be capable of delivering several tens of A/sq-cm at low threshold voltages and will be used in traveling wave tubes produced by the industrial partner.The approach involves pulsed laser deposition of the constituent materials into 10-nm sized pores of porous alumina and testing them at the facilities of the industrial partner.The broad impacts are varied. The commercial impact is in the field of cold cathode technology that has applications in wireless systems including cell phones, base stations, satellite communications, flat panel displays, etc. The educational impact is in the training of graduate students as well as outreach efforts to mostly African American 9th and 12th graders through the Richmond Area Program for Minorities in Engineering (at Virginia) and to other under-represented groups though the Ethnic Engineers program at Cincinnati. The fabrication method is environment friendly and the economic/societal impact is in job creation in the high tech area of microwave products.
目的和方法:本研究的目的是合成有序的稀土硫化物纳米线自组装阵列。这将产生具有低功函数 (~ 1 eV) 和高熔点 (~ 2000 C) 的高效场发射器的密集阵列。它们将能够在低阈值电压下提供数十 A/sq-cm 的电流,并将用于工业合作伙伴生产的行波管。该方法涉及将成分材料脉冲激光沉积到 10 纳米大小的多孔氧化铝孔中,并在工业合作伙伴的设施中对其进行测试。广泛的影响是多种多样的。商业影响在于冷阴极技术领域,该技术应用于手机、基站、卫星通信、平板显示器等无线系统。教育影响在于研究生培训以及通过里士满地区工程少数群体计划(弗吉尼亚州)向大多数非裔美国 9 年级和 12 年级学生以及通过辛辛那提民族工程师计划向其他代表性不足的群体进行的推广工作。该制造方法是环境友好的,其经济/社会影响在于在微波产品高科技领域创造就业机会。
