The continued growth of mobile and interactive computing requires devices manufactured with low-cost processes, compatible with large-area and flexible form factors, and with additional functionality. We review recent advances in the design of electronic and optoelectronic devices that use colloidal semiconductor quantum dots (QDs). The properties of materials assembled of QDs may be tailored not only by the atomic composition but also by the size, shape, and surface functionalization of the individual QDs and by the communication among these QDs. The chemical and physical properties of QD surfaces and the interfaces in QD devices are of particular importance, and these enable the solution-based fabrication of low-cost, large-area, flexible, and functional devices. We discuss challenges that must be addressed in the move to solution-processed functional optoelectronic nanomaterials.
移动和交互式计算的持续发展需要使用低成本工艺制造的设备，这些设备应与大面积和灵活的外形因素兼容，并具有附加功能。我们综述了利用胶体半导体量子点（QD）设计电子和光电设备方面的最新进展。通过 QD 组装的材料的性能不仅可以通过原子组成来调整，还可以通过单个 QD 的尺寸、形状和表面功能化以及这些 QD 之间的通信来调整。QD 表面的化学和物理性质以及 QD 器件中的界面性质非常重要，它们使得能够制造出低成本、大面积、灵活和功能化的设备。我们讨论了在向基于溶液的功能性光电纳米材料发展过程中必须解决的挑战。
