Abstract
We measured terahertz (THz) emission from the vertically aligned indium arsenide (InAs) nanowires using THz time-domain spectroscopy. The photoexcited InAs nanowires were grown by metalorganic chemical vapor deposition on type <;111> silicon substrate. Experimental results shows that THz emission mechanism of InAs nanowires are very different from that of bulk InAs substrates.
