The electronics industry is facing two critical challenges; the increasing complexity to make smaller, faster high performance components and the “electronics everywhere” phenomena requiring portable, low power, niche roles of electronic components. Both of these challenges require fundamental innovations and understanding of electronic processes at interfaces. I will describe advances made in our ability to manipulate and measure organic and molecular interfaces at the nanometer scale and the impact on the resulting electronic performance. In particular, I will focus on the measurement advances made in molecular electronics, highlighting our understanding of the interface science and characterization. This talk will contain two illustrative case studies demonstrating the impact of interface engineering on charge trapping memory devices and spin-based paradigms. Organic molecules are advantageous for trapped charge memory devices due to their small size, discreet nature, and tunability. I will describe a series of advances in creating and characterizing molecular memory devices incorporating a novel ruthenium based redox-active molecule as the charge storage layer.(1) Spin-based paradigms are increasingly important for future electronics and of special interest is the manipulation of spin in organic materials. I will describe a series of advances that examine the impact of organic monolayers on the ferromagnetic oxide interface and the role interface engineering can play in organic spintronics.(2) 1.“Non-volatile memory devices with redox-active diruthenium molecular compound” S.
