Abstract:采用化学气相沉积(CVD)方法,在无催化剂的条件下,生长出了锑掺杂的超长、大尺寸ZnO微米线.测试表明微米线的平均长度可达1~2.5
   cm,微米线中锑元素的含量约为3.1%(n/n).此外,将挑选出的单根锑掺杂ZnO微米线以银浆为电极制作成热电发电机,并研究了微米线长度和微米线
   直径对器件输出性能的影响.研究表明当器件两电极之间的温差为20 K且两电极间微米线的长度为1.6
   cm时,器件能够输出的最大电压和最大输出功率分别约为36 mV和10.8
   nW,微米线的赛贝克系数约为-1.80mV·K~(-1).此外,热电器件的输出电压随着微米线长度的增加而增大,随微米线直径的增加而减小.
