A template is a great tool for making an object of a particular size and shape, but it works only if the template fills completely. Shin et al. show that ions race to fill the pores in the template during template-assisted electrodeposition of nanowires. When fast-growing wires fill the template, however, neighboring wires stop growing, creating instabilities in the wire growth. The authors show that they can overcome this problem of “diffusion-limited” deposition by making the template hotter at one end and colder at the other.
