Abstract

The authors report the growth of needle-like high density quaternary Zn0.87Cd0.13Se0.98Te0.02nanotips on oxidized Si(100) substrate. It was found that average length and average diameter of the nanotips were 1.3 μm and 91 nm, respectively. It was also found that the as-grown ZnCdSeTe nanotips exhibit mixture of cubic zinc-blende and hexagonal wurtzite structures. Furthermore, it was found that the operation speeds of the fabricated ZnCdSeTe nanotip photodetector were fast with turn-on and turn-off time constants both less than 2 s.

摘要

作者在氧化硅（100）衬底上报告了针状高密度四元 Zn0.87Cd0.13Se0.98Te0.02纳米尖的生长。发现纳米尖的平均长度和平均直径分别为 1.3μm 和 91nm。还发现所生长的 ZnCdSeTe 纳米尖表现出立方闪锌矿和六方纤锌矿结构的混合物。此外，还发现所制造的 ZnCdSeTe 纳米尖光电探测器的工作速度很快，开启和关闭时间常数均小于 2 秒。
