Perspectives and challenges in nanoscale device modeling
In this paper, we discuss the role of adequate modelling tools in the development of nanoelectronic technology and devices, including both down-the-roadmap Complementary Metal-Oxide-Semiconductor (CMOS) technology and alternative nanodevices. Such tools can enable understanding of the relevant physical mechanisms on the one hand, and performance evaluation and optimization of device structures,...
متن کاملModeling and Numerical Challenges in Nanoscale Device Engineering
In spite of considerable research effort and progress, high quality simulation-based design of nanoscale emerging devices still presents formidable modeling and computational challenges. Characterization of nanoscale emerging devices needs to be addressed via quantum simulations that need to account for: (i) information of the material at the atomistic level, (ii) multiscale aspects of electron...
متن کاملStatus and perspectives of nanoscale device modelling
During the meetings of the theory and modelling working group, within the MEL-ARI (Microelectronics Advanced Research Initiative) and NID-FET (Nanotechnology Information Devices–Future and Emerging Technologies) initiatives of the European Commission, we have been discussing the current status and the future perspectives of nanoscale device modelling. The outcome of such a discussion is summari...
متن کاملQuantum capacitance in nanoscale device modeling
Expressions for the “quantum capacitance” are derived, and regimes are discussed in which this concept may be useful in modeling electronic devices. The degree of quantization is discussed for oneand two-dimensional systems, and it is found that two-dimensional (2D) metals and one-dimensional (1D) metallic carbon nanotubes have a truly quantized capacitance over a restricted bias range. For bot...
متن کاملNanoscale device modeling: the Green’s function method
The non-equilibrium Green’s function (NEGF) formalism provides a sound conceptual basis for the devlopment of atomic-level quantum mechanical simulators that will be needed for nanoscale devices of the future. However, this formalism is based on concepts that are unfamiliar to most device physicists and chemists and as such remains relatively obscure. In this paper we try to achieve two objecti...
