Controlled Integration of Functionalized Janus-Nanoparticles

分子电子学的一个主要目标是将纳米元件，如分子功能化的金属纳米颗粒，集成到传统的CMOS电路中，以实现额外的功能。然而，今天的挑战是通过设计精确地控制分子-金属结的电子功能。我们的目标是通过在异金属纳米电极之间定向固定二价双功能(Janus类型)纳米颗粒来解决这个问题。因此，有机/金属界面将以这样的方式被调谐，即通过单个Janus纳米颗粒的定向组装可靠地产生二极管功能。此外，可以预见有机分子的原位自组装，以建立与对电极具有可控接触的分子导线。与此同时，这种有机分子导线蕴含着一种内在的开关功能，可以通过光学或电气手段来解决。这样，最终将产生一个具有开关和整流能力的功能单元，它将作为新型混合分子电子器件的概念验证。

One major goal of molecular electronics is the integration nanoelements, like molecularly functionalized metal nanoparticles, into traditional CMOS circuitry to enable additional functionality. However, todays challenge is to control exactly the electronic function of the molecule-metal junction by design. We aim to solve this problem by the directed immobilization of divalent bifunctional (Janus-type) nanoparticles in between heterometallic nanoelectrodes. Hereby, the organic/metal interfaces will be tuned in such a way that a diode function is created reliably by directed assembly of a single Janus-nanoparticle. Furthermore, the self-assembly of organic molecules in situ in order to build a molecular wire with controlled contact to the counter-electrode is foreseen. At the same moment, this organic molecular wire implies an intrinsic switching functionality which can be addressed by optical or electrical means. Thus, finally a functional unit with switching and rectifying ability will be created, which shall serve as a proof-of-concept for a new type of hybrid molecular electronic devices.
