Sentences with phrase «efficient than silicon»

Although circuits made with single - walled carbon nanotube are expected to be more energy - efficient than silicon ones in future, their drawbacks in field - effect transistors, such as high power dissipation and less stability, currently limit their applications in printed electronics, according to Dodabalapur.
