Nanodevices could use quantized current to operate future electronics

Abstract:
For the past several decades, virtually all electronics devices have been based on the CMOS logic system, which uses semiconductors and transistors to form digital circuits. However, researchers today are investigating the use of novel materials and technologies to create superior circuitry, which would lead to smaller, faster and smarter computers, cell phones, and other devices.

Most recently, scientists Wancheng Zhang, Nan-Jian Wu, and Fuhua Yang from the Chinese Academy of Sciences in Beijing have designed logic gates—a basic component of digital circuits—that use the quantization of electric current to perform operations. The recent development of two unique nanodevices has enabled scientists to control the flow of individual electrons, allowing the team to propose novel universal logic gates that are more compact than conventional logic gates.
