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…
Simulation and optimisation of terahertz emission from InGaAs and InP photoconductive switches
J. Lloyd-Hughes, E. Castro-Camus, M. B. Johnston
We simulate the terahertz emission from laterally-biased InGaAs and InP using a three-dimensional carrier dynamics model in order to optimise the semiconductor material. Incident p…
