The charge transport of molecular selfassembled monolayers (SAMs) is studied using various characterization platforms: nanoscale device, micro-via hole structure device, and a structure for conducting atomic force microscopy (CAFM). Micro-via hole structure devices are fabricated to study conduction mechanism of alkanethiol SAMs and particularly the device yield study. The device yield of micro-via hole structure devices was found as ~ 1 % out of more than 13,000 fabricated devices. A criteria of determination of working devices will be proposed. Using the structure for CAFM, we study the effect of molecular chain-to-chain coupling under the influence of tip contact to SAM. Advantages and limitations of these platforms for characterizing molecular junctions will be discussed. |
