As electronic devices and integrated circuits get smaller and smaller, eventually quantum-mechanic effects take over. As Saito discusses in his Perspective, results reported by Collins et al. in the same issue demonstrate the use of carbon nanotubes to create nanometer-scale devices known as diodes. Rather than fighting the effects of quantum mechanics, such devices make excellent use of quantum effects on the nanometer scale.
