DB04: Multiphysics Modelling in Radio Frequency Nanoelectronics (2)

Friday, August 22  09:40-10:40,  Room #21

Session Chairs: Peter Russer, Wenquan Che

The future development of radio-frequency nanoelectronics will be characterized by a further increase of integration density, higher frequencies, lower power consumption and enhanced functionality. Wireless technology and vehicular technology and the need for high-speed digital circuits are major drivers for the increased demand for high-frequency and optoelectronic devices. The design of radio-frequency nanoelectronic devices and systems requires advanced multi-physics and multi-scale design tools. Multi-physics modeling is achieved by a synoptic combination of electromagnetic, mechanical, acoustic, thermal and quantum mechanical effects governed by Maxwell’s equations, Hamiltonian systems in point mechanics, elasticity theory and acoustics, heat-conduction, electronic transport (Boltzmann equations), and the Schroedinger equation. Methods of solution comprise analytic tools (e.g. integral equation (IE) methods and method of moments (MoM)), numerical tools (finite difference (FD), finite difference time domain (FDTD), finite difference frequency domain (FDFD), transmission line matrix (TLM) wave digital filter (WDF) methods), and hybrid combinations of these methods. To achieve an accurate and efficient analysis of problems with widely separated time scales the method of multi-time partial differential equations are of interest. For nano-patterned structures exhibiting extremely large aspect ratios in their geometry also space multi-scale methods will be applied.
