Ion track, nanoporous membranes were employed as templates for the preparation of CdTe nanowires. For this purpose, electrochemical deposition from a bath containing Cd and Te ions was employed. This process leads to high aspect ratio CdTe nanowires, which were harvested and placed on a substrate with lithographically patterned, interdigitated electrodes. Focused ion beam-induced metallization was used to produce individual nanowires with electrical contacts and electrical measurements were performed on these individual nanowires. The influence of a bottom gate was investigated and it was found that surface passivation leads to improved transport properties.
离子径迹纳米多孔膜被用作制备碲化镉纳米线的模板。为此，采用了从含有镉离子和碲离子的镀液中进行电化学沉积的方法。这个过程会产生高纵横比的碲化镉纳米线，这些纳米线被收集起来并放置在具有光刻图案化叉指电极的基板上。聚焦离子束诱导金属化被用于制造带有电触点的单个纳米线，并对这些单个纳米线进行电学测量。研究了底部栅极的影响，发现表面钝化会改善传输性能。
