Analysis of al2o3 - si2o short fiber structure and length diameter ratio
短纤维结构与长径比分析
Since the discovery of cnt ’ s and find that cnts have small diameter and high length diameter ratio and can be look as one - demission material , it can be used as emission emitter of fed . especially , the aligned cnts array can be seen innumerable single cathodes which are lined regularly and form array . so growing aligned cnts array in selective area is the key technology to product cnts fed , which is also the necessary condition of cnts micro - electronics device
自碳纳米管发现以来,由于碳纳米管的直径很小、长径比大,故可视为准一维纳米材料,可作为场发射平板显示的尖端发射体,特别是定向碳纳米管阵列可看成是无数根单尖阴极规则的排列起来形成阵列式,是理想的场发射平板显示器的尖端发射体。
