Molecular electronics explores the intrinsic properties of materials at the molecular level. However, molecular electronics has suffered from a low device yield problem. To improve the device yield, various methods have been proposed, such as by utilizing an intermediate protecting layer, direct metal transfer, etc. In this talk, I will explain our research works on functional high yield molecular electronic devices. Specifically, I will explain (1) rectifying molecular electronic devices of ferrocene-alkanethiolate molecules which showed asymmetric electrical transport characteristics, and (2) photoswitching devices of diarylethene molecules which showed two electrical states (a high and a low conductance state) with a discrepancy of an order of magnitude when exposed to UV or visible light. In particular, these functional molecular devices were demonstrated not only on rigid substrates but also on plastic flexible substrates with a high device yield. |
