One of the main motivations for the great interest in semiconductor nanowires is the possibility of easily growing advanced heterostructures that might be difficult or even impossible to achieve in ...

We present an ErAs:InAlGaAs photoconductive antenna receiver optimized for 1030 nm probe pulses, excited at very high THz average power (24 mW). We measure a dynamic range of 92 dB in a 10 s ...

With increasing interest in nanowire-based devices, a thorough understanding of the nanowire shape is required to gain tight control of the quality of nanowire heterostructures and improve the ...

Abstract: Constrained by Abbe diffraction, terahertz time-domain spectroscopy utilizing photoconductive antennas (PCA) is limited to submillimeter spatial resolution and requires several hours to ...
