项目摘要
We propose to develop prototypical combinational logic machines using electronic quantum states of self-assembled exchange-coupled few nanodot arrays. Small core Au clusters will be functionalized with suitable ligands. Nanoelectrodes will electrically address the states of the array formed by assembling a few dots. Theory will determine the possible states taking into account the Coulomb blocking of charge transfer, the different aspects of disorder and the role of the ligands. The design seeks to go beyond switching arrays and to integrate directly Boolean operations for the implementation of logic gates, such as half- and full-adders, on a few-dot array. We aim to fabricate a demonstrator of such logic gates working at room temperature, to perform electron transport studies, to verify the computational results, and to use theory to further optimize the performance. For this, functional Au clusters with well-defined core-sizes of less than 2 nm will be synthesized. These will be arranged by directed self-assembly processes between lithographically predefined and, in a second stage, tailored nanoelectrodes in order to fabricate multiple terminal devices. Using this approach nanometer scale integration of devices for information processing at the hardware level will be demonstrated. A longer-term goal is to extend the capability of the design to that of a finite state logic machine.
我们建议开发原型组合逻辑机使用自组装交换耦合的几个纳米点阵列的电子量子态。小核Au簇将用合适的配体官能化。纳米电极将以电的方式处理由几个点组成的阵列的状态。理论将确定可能的状态,考虑到电荷转移的库仑阻塞,无序的不同方面和配体的作用。该设计旨在超越开关阵列,并直接集成逻辑门,如半和全加器,在几个点阵列的实施布尔运算。我们的目标是制作一个演示这种逻辑门在室温下工作,进行电子输运研究,验证计算结果,并使用理论来进一步优化性能。为此,功能Au簇与明确定义的核心尺寸小于2纳米将被合成。这些将通过光刻预定义的和在第二阶段定制的纳米电极之间的定向自组装过程来布置,以便制造多个终端设备。使用这种方法,纳米级集成的信息处理设备在硬件水平将被证明。一个长期的目标是将设计的能力扩展到有限状态逻辑机。
