ERA NanoSci - Interfacing single molecules via nanoparticle networks

点击翻译按钮获取中文摘要

We approach the problem of interfacing nanoscopic molecules with macroscopic electrodes by using nanoscale intermediates. Our multiple-scale architecture, based on two-dimensional arrays of nanoparticles and metallic nanowires, provides reliable and robust access to electrical, optical and mechanical properties of molecular systems. We will initially explore our device platforms for benchmark molecules to obtain fundamental knowledge on hard-soft interfacing. Next, we interface spin transition systems to obtain dramatic changes of device properties under external stimuli (temperature, stress, electric fields), addressing the fascinating challenge to contact a molecule without losing its functionality. Our results will enable us to select molecular candidates for future sensor applications in functional arrays. Specifically, we will explore a hydrogen gas sensing device, fully based on functional nano-objects (nanoparticles and functional molecules).
