本文综述了局部功能化材料的收费。使用各种扫描探针显微镜（SPM）技术的微观分析和操作的电荷揭示了静态，准静态/准动态和动态的电荷行为。电荷敏感的SPM已经允许在电子设备中的功能化电荷的分布的可视化。当在存储器系统中用作位数据时，电荷可以由SPM操作。这里讨论准静态/准动态电荷的行为。在数据写入过程中，引入了空间分散的电荷，而不是快速的注入速率，但技术问题可以通过使用纳米结构来解决。使用SPM的仔细充电操作应实现具有大于Tbit/inch 2的密度的存储器。动态电荷已被引入物理分析和化学过程中。虽然可观察到的时间尺度是有限的SPM系统响应时间的顺序为几秒钟，动态，如光子诱导的电荷重新分布和探针辅助化学反应进行观察。
This paper reviews charges that locally functionalize materials. Microscopic analyses and operation of charges using various scanning probe microscopy (SPM) techniques have revealed static, quasi-static/quasi-dynamic and dynamic charge behaviours. Charge-sensitive SPM has allowed for the visualization of the distribution of functionalized charges in electronic devices. When used as bit data in a memory system, the charges can be operated by SPM. The behaviour of quasi-static/quasi-dynamic charges is discussed here. In the data-writing process, spatially dispersive charges rather than a fast injection rate are introduced, but the technical problems can be solved by using nanostructures. Careful charge operations using SPM should realize a memory with a larger density than Tbit/inch2. Dynamic charges have been introduced in physical analyses and chemical processes. Although the observable timescale is limited by the SPM system response time of the order of several seconds, dynamics such as photon-induced charge redistributions and probe-assisted chemical reactions are observed.
