Lateral SiOx Tunnel Barrier Formation for Si-based Tunnel Transistor Using Scanned Probe Oxidation
K Morimoto, L Morita, K Ohnaka, John A. Dagata
Tunneling transistors designed with a lateral tunnel barrier between source and drain electrodes have attracted much attention recently as an approach to silicon-compatible nanoelectronics. In order to realize this device, the lateral tunneling barrier must be fabricated with a width of less than 10-nm. Fabrication methods of a lateral tunnel junction using scanned probe microscope (SPM) oxidation were described previously, but, so far, research efforts have focused on forming a metal/insulator junction as with the Nb/NBOx system. In this work, we demonstrate preliminary results towards fabricating and evaluating a lateral Si/SiOx tunneling junction on an ultra-thin Si layer by SPM oxidation.
