Computational Study of Graphene Nanoribbon Resonant Tunneling Diodes
The structural effects of different graphene nanoribbon resonant tunneling diodes (GNR-RTDs) are investigated under different temperatures. Although the W-shape structure outperforms the H-shape structure in term of the peak current, the peak-to-valley ratio of the H-shape is higher than the W-shape due to the smaller peak currents of the former. Furthermore, the effects of the channel length and the contact's bandgap of the W-shape GNR RTDs on device performance are studied and their detailed device physics is also provided in this work.
