Description
Summary:<p>Abstract</p> <p>The authors report the growth of needle-like high density quaternary Zn<sub>0.87</sub>Cd<sub>0.13</sub>Se<sub>0.98</sub>Te<sub>0.02</sub>nanotips on oxidized Si(100) substrate. It was found that average length and average diameter of the nanotips were 1.3 &#956;m 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.</p>
