New Publication – The influence of surfaces on the transient terahertz conductivity and electron mobility of GaAs nanowires

Picture2

In research led by Hannah Joyce (University of Cambridge), and colleagues at the University of Oxford and the Australian National University we have reported an in-depth terahertz study of the influence of surfaces on carrier recombination in nanowires.

By performing power-dependant and diameter-dependant measurements, Hannah determined the surface recombination velocity in GaAs nanowires. Given the huge surface-area-to-volume ratio in nanowires, this is a key property and one which is essential to understanding the electronic performance in this nanomaterial.
