Project (with scholarship)
Co-supervisors: Dr Zhou Xing and Dr Ang Lay Kee, Ricky For details: please send email to: exzhou@ntu.edu.sg or elkang@ntu.edu.sg Synopsis: Carbon nanotube (CNT) is currently considered as one of the future building blocks for the next generation nanoelectronics, such as CNT field-effect transistors (CNTFETs) using single-wall CNT (SWCNT) as demonstrated by IBM since 2001. In addition to the small size in nanometer range, CNT has superior properties that may solve the technological barriers faced by the mainstream CMOS silicon technology. Currently, the state-of-the-art CNTFETs can have 3-4 times higher drive current than the MOSFETs counterpart at an overdrive of 1 V, thus providing higher transconductance. However, the scaling of CNTFETs does not follow the traditional transistor scaling of silicon MOSFETs, which will require a complete revision in order to design CNTFET-based nanoelectronics. Due to the unique properties of CNT in the nanometer scale, quantum-mechanical (QM) or first-principle calculation is usually required to understand the scaling of CNTFETs. It is found experimentally that the switching and transport in CNTFETs is controlled by the Schottky Barrier (SB) at the CNT-metal contact. The properties of SB in CNTFETs are sensitive to various factors such as line-up of the CNT bands, adsorption at the contacts, and the 3D electrostatic effects. Thus, it is imperative that a consistent QM model be developed to extract the scaling laws in the atomistic level. In conventional ULSI circuit design, top-down approach is used in modeling transistors at the circuit/system level. Scaling of CMOS technology has already reached the level in which transistors are in the nanometer regime. To apply the bottom-up atomistic models for CNTFETs to the top-down approach in circuit design, the atomistic-level abstraction needs to be bridged to the “compact” device level suitable for circuit simulation. However, the “handshake” of these two approaches, traditionally belonging to different domains, is not trivial, which requires a “dual-representation” at the same level such that lower (atomic) level physics and be “propagated” to the higher (compact) level of abstraction. This type of multi-scale modeling serves as one of the grand challenges in the coming nanoelectronics era. In summary, the project is aimed at developing first-principle models to provide a comprehensive scaling of CNTFETs and discover its unique advantages that can not be found in the traditional MOSFETs. The integration of the developed quantum models to the device level for circuit simulation will be explored. |
