1000 single nano-tube transistors on a chip. Credit: Aalto University Scientists at Aalto University, Finland, and Nagoya University, Japan, have found a new way to make ultra-clean carbon nanotube transistors with superior semiconducting properties. Single-wall carbon nanotubes (SWCNT) have found many uses in electronics and new touch screen devices. Carbon […]

Researchers used nonlinear resonators to mold a circuit array whose function proved to be inherently robust against defects that would normally interrupt signal transmission.

Charge screening in ferroelectric Pb(Zr,Ti)O3 nanorods was used to control their domain pattern. The c-domain fraction markedly increased with as the rod width decreased, while the a-domain formation prevailed by metallization of their sidewall. All the observed results could be explained by the depolarizing field, arising from the imperfect charge […]
