SEM and TEM images and
characteristic curves of the isolated CdS microrope. (a) SEM image of an isolated CdS microrope and a pair of Pt microleads fabricated with focused ion beam deposition. The inset shows the TEM image of the CdS microrope, which is composed of twisted CdS nanowires. (b)
I-V characteristic curves of the isolated CdS microrope at different temperatures from 360 down to 60 K; the curves are symmetric.
