Influence of surface passivation on ultrafast carrier dynamics and terahertz radiation generation in GaAs
J. Lloyd-Hughes, S. K. E. Merchant, F. Lan +4
The carrier dynamics of photoexcited electrons in the vicinity of the surface of (NH4)2S-passivated GaAs were studied via terahertz (THz) emission spectroscopy and optical-pump THz…
Charge trapping in polymer transistors probed by terahertz spectroscopy and scanning probe potentiometry
J. Lloyd-Hughes, T. Richards, H. Sirringhaus +3
Terahertz time-domain spectroscopy and scanning probe potentiometry were used to investigate charge trapping in polymer field-effect transistors fabricated on a silicon gate. The h…
Detecting the full polarisation state of terahertz transients
E. Castro-Camus, J. Lloyd-Hughes, M. D. Fraser +3
We have developed a detector which records the full polarisation state of a terahertz (THz) pulse propagating in free space. The three-electrode photoconductive receiver simultaneo…
Polarisation-Sensitive THz Detectors
M. B. Johnston, E. Castro-Camus, J. Lloyd-Hughes +3
We have developed a detector of coherent terahertz (THz) radiation that can recover the full polarisation state of a THz transient. The device is three-contact photoconductive rece…
Photoconductive detection of arbitrary polarised terahertz pulses
E. Castro-Camus, J. Lloyd-Hughes, M. B. Johnston +3
To perform polarization sensitive THz-TDS, it is necessary to be able to measure two (preferably orthogonal) electric field components of a terahertz transient. We have developed a…
Polarisation-sensitive terahertz detection by multicontact photoconductive receivers
E. Castro-Camus, J. Lloyd-Hughes, M. B. Johnston +3
We have developed a terahertz radiation detector that measures both the amplitude and polarization of the electric field as a function of time. The device is a three-contact photoc…
