Surface Modification and Nanojunction Fabrication with Molecular Wires
Abstract
Electron transfer has been a core subject in science and technology. The overarching goal of this AOARD project is the development of molecular wires with metal-metal bonds, and ultimately devices based on the unique electron transporting behaviors across the nano-objects. One of the first steps is to tailor the axial ligands for the molecular wires, specifically, to make contact between molecules and the electrode. For the previous AOARD project (FA2386-12-1-4006), the Taiwan and US PI/co-PIs studied both metal string (EMAC) and diruthenium wires containing axial ligands suitable for attachment to gold and silica oxide surfaces. Platforms of conductance measurements for single-molecule studies were developed by the Taiwan team. The highlight of the current project period is the fabrication of high-performance top-gated nanowire molecular flash memory based on diruthenium wires (ACS Appl. Mater. Interfaces 2015, 7, 27306-27313).Additional work to be published investigates the charge trapping mechanism at molecule-oxide interfaces (J. Phys.: Condens. Mat. 2016, 28, In press).
