ABSTRACT
Single electron devices have specific characteristics and properties, particularly the existence of periodic Coulomb blockade oscillations, a high charge sensitivity and an operation based on charge quantization. Many investigations have been done to take advantage of them. However, there are several challenging issues to face before any concrete application. Here, we overview the potential of these devices and discuss their merits and drawbacks. Although some niche applications exist, it is concluded that their future should be thought in hybrid association with CMOS.
