Carbon Nanotube Based CMOS Devices and Integrated Systems by Professor Lian-Mao Peng

ABSTRACT:  Carbon nanotube (CNT)-based electronics has been considered one of the most promising candidates to replace Si complementary metal-oxide-semiconductor (CMOS) technology, which will soon meet its performance limit. Prototype device studies on individual CNTs revealed that CNT based devices have the potential to outperform Si CMOS technology in both performance and power consumption, especially at sub-10 nm technology nodes, which are close to the theoretical limits; and various optoelectronic device such as light-emitting diodes, photodetectors and photovoltaic (PV) cells have been demonstrated. Very recently, both p-type devices and integrated systems were fabricated using CNT films. However, the key performance metrics demonstrated by these devices are still substantially lower than those of conventional semiconductor based devices. In this talk, I will discuss the use of randomly oriented CNT film to build CNT CMOS and optoelectronic devices, and show that the performance of CNT film devices and systems can be dramatically improved by optimizing the material purity, device structure and fabrication processes, thus yielding CNT devices with outstanding performance comparable to that of Si CMOS and ICs working in the GHz regime, and integrated electronic and optoelectronic systems for communications between nanoelectronic circuits using CNT devices.
