Emerging Phenomena-dependent Non-CMOS Nanoelectronic Devices - What Are They?

Complementary metal oxide semiconductor (CMOS) transistors have reached the nanometer geometry scale (1–100 nm) where they are difficult to be scaled anymore due to essentially quantum mechanical properties effects. This paper discusses emerging non-CMOS nanoelectronic devices (nanodevices) that could potentially be able to circumvent this problem. First we propose a nanodevice taxonomy which classifes them according to the physical phenomena driving their operations into electrical, magnetic, and mechanical nanodevices. Thereafter, a detailed analysis and comparison of the difference nanodevice classes are presented, including structures, advantages, disadvantages and potential applications.
