We have used terahertz spectroscopy to measure the conductivity and time-resolved photoconductivity of a range of semiconducting nanostructures. This article focuses on our recent terahertz conductivity studies on semiconductor nanowires and single walled carbon nanotubes.
We have improved the stability and performance of terahertz photoconductive (Auston) switches using a combination of (NH4)2S surface passivation and silicon nitride (Si3N4) encapsulation. The passivation and encapsulation processes increased the average terahertz power generated four-fold.
Although surface acoustic wave (SAW) devices using quartz and LiNbO3 have proven highly successful, manufacturability would be considerably eased if SAW devices could be readily integrated with semiconductor devices. In a recent paper, Lee et al. proposed Mg-doped epitaxial GaN as suitable for SAW devices integrated with other III-V materials. The piezoelectric constant, or electromechanical coupling...
