Ultrafast metal-insulator-multi-wall carbon nanotube tunneling diode employing asymmetrical structure effect

Abstract:

Ultra-fast diode structures based on non-semiconductive materials employing tunneling mechanism have been investigated. Applying the structurally asymmetric effect of multi-wall carbon nanotube (MWCNT) to a vertical metal-insulator-MWCNT (MIC) tunneling diode structure, the ‘on-off’ ratio (∼104) and the current density (38.2 MA/cm2) are drastically enhanced compared to those of conventional metal-insulator-metal (MIM) tunneling diodes. The electrical characteristics are stable up to 423 K. Ex...
