Abstract – In this work, we statistically study characteristic fluctuation of 16-nm-gate high-/metal gate (HKMG) MOSFETs by random-discrete-dopants (RDDs) inside silicon channel and random-interface-traps (RITs) at high-k/silicon interface. Randomly generated devices with three-dimensional (3D) RDDs [...]

Electromechanical models of nano-electromechanical devices are usually implemented with specifically developed mathematical software and these models are not easily compatible with circuit simulation software. However, in order to use a nano-device as a sensor, a [...]
Silicon has found considerable application in precision MEMS devices because it provides desirable high frequency and quality factor characteristics. Usually, MEMS resonators are built from single crystal silicon with proven long-term stability. It is experimentally [...]
The reliable estimation of squeeze-film damping (SQFD) is a prerequisite for the design of many microelectromechanical systems (MEMS). The proper operation of several MEMS devices (e.g. accelerometers) often depends crucially on the damping forces, i.e. [...]
