Abstract Details

2010, Master of Sciences (Engineering), Case Western Reserve University, EECS - Computer Engineering.
Nano-electromechanical systems (NEMS) switches provide a promising alternative to conventional CMOS technology in terms of building digital circuits. These switches can theoretically operate at much lower power and in extremely harsh environments (in terms of temperature and radiation) where conventional CMOS technology fails to work reliably. Digital circuit design using NEMS technology can utilize innovative switch structures due to the freedom offered by the three-dimensional mechanical structure and a diverse set of materials. Silicon carbide (SiC) is a promising material for NEMS switch design due to its electrical conductivity and ability to operate in harsh environments such as space shuttle and combustion engine. In this work, novel NEMS structures for SiC are explored in two different areas: multiplexing and multi-valued memory cells. In each scenario, multiple alternative designs are developed, verified through electrical and mechanical analysis, and compared in terms of multiple design metrics. For each structure, an appropriate circuit-compatible model is developed and electrically simulated. Mathematical analysis is performed to predict the behavior of each design. The simulation results confirm correct functional behavior and provide estimates on switching parameters.
