Abstract

The one-dimensional nanostructures have been used as the electrode to decrease the operation voltage where strong electric field is needed to function the device in the gaseous electronics. In this letter, a novel electrode scheme is proposed to generate high field intensity at extremely low applied voltages. Through the theoretical calculation, we shall demonstrate some specific cases of the electrode systems where the fields can reach 106, 109, and 1011 V/m orders of magnitudes at the applied voltage as low as 10mV. The imaginary cases could be realized by various fabrication technologies.
