Idea of utilizing individual molecules as the electronic components in future ultrahigh-density electronic devices has generated tremendous attention. I will explain recently developed understanding on the electrical transport characteristics through various types of molecular junctions on flat or flexible substrates [1-3]. In particular, obtaining transistor action from molecular orbital control has been the outstanding challenge of the field of molecular electronics nearly since its inception. In this talk, I will demonstrate a direct electrostatic modulation of orbitals in a molecular transistor configuration in electromigration nanogap [1] or in mechanically-controllable break junction (MCBJ) [2]. I will also demonstrate functional devices such as diodes or photoswitches at the molecular-scale on both rigid and flexible substrates [3]
I will also present a brief summary on general characteristics of the materials, device structures, and switching mechanisms used in polymer-based non-volatile memory devices. Strategies for performance enhancement, integration, and advanced architectures in these devices will be presented [4].
