Conduction processes in metal–insulator–metal diodes with Ta₂O₅ and Nb₂O₅ insulators deposited by atomic layer deposition

Creator:

Alimardani, Nasir, McGlone, John M., Wager, John F., and Conley, John F., Jr.

Abstract:

Metal–insulator–metal diodes with Nb₂O₅ and Ta₂O₅ insulators deposited via atomic layer deposition are investigated. For both Nb₂O₅ and Ta₂O₅, the dominant conduction process is established as Schottky emission at small biases and Frenkel–Poole emission at large biases. Fowler–Nordheim tunneling is not found to play a role in determining current versus...

Investigation of metal-insulator-metal (MIM) and nanolaminate barrier MIIM tunnel devices fabricated via atomic layer deposition

Creator:

Alimardani, Nasir

Abstract:

Metal-insulator-metal (MIM) tunnel devices have been proposed for high speed applications such as hot electron transistors, IR detectors, optical rectennas for IR energy harvesting, and backplanes for LCDs. The majority of these applications require highly asymmetric and non-linear current versus voltage (I-V) behavior at low applied voltages and ultra-high frequencies....
