Electronic devices made with organic molecules may one day play an important role in integrated circuits. However, the research is still in its infancy. The mechanically controlled break-junction technique allows the measurement of the current through a single molecule junction. The
current–voltage relations indicate a nonlinear conductance. Information about the junction can be provided by comparative studies of different molecules. It turns out that the conduction properties depend strongly on the molecular structure. This, in turn, encourages the idea of tailoring
the electronic properties by an appropriate design of the molecule.
使用有机分子制造的电子设备可能有一天在集成电路中发挥重要作用。然而,这方面的研究仍处于起步阶段。机械控制断裂连接技术允许测量通过单个分子连接的电流。电流-电压关系显示非线性导电性。通过比较不同分子的研究可以提供有关连接的信息。结果表明导电性质严重依赖于分子结构。这反过来鼓励通过适当设计分子来定制电子性能的想法。
