Comparative Analysis of Threshold Voltage Variations in Presence of Random Channel Dopants and a Single Random Interface Trap for 45 nm N-MOSFET as Predicted by Ensemble Monte Carlo Simulation and Existing Analytical Model Expressions
Comparative analysis of analytical model and full Ensemble Monte Carlo simulation which takes into account both the short-range and the long-range coulomb interaction in the presence of random dopants and random traps is performed.
Analytical Solution of Surface Potential for Un-Doped Surrounding-Gate MOSFET
Surrounding-Gate MOS transistors are seen as viable slternative to the problems of bulk MOSFET in deep sub-micron region. However modeling of drain current and capacitances, like other MOS structures require solution of an implicit equation. [...]
Monte Carlo Simulation of Impact of Random Telegraph Noise in 45 nm MOSFET Due to Coupled Effects of Random Interface and Oxide Traps With Random Channel Dopant Distributions
This paper presents a 3-D Ensemble Monte Carlo ( EMC ) based simulation for 45 nm gate length MOSFET to account for the fluctuations in drain current (saturation) and threshold voltage as causes of reliability [...]
Self – Heating Effects in Nanowire Transistors
We investigate the role of self-heating effects on the electrical characteristics of a silicon nanowire transistor using a 3-D Monte Carlo device simulator that includes self-consistent solution of the energy balance equations for both acoustic [...]
A Solid Electrolyte Valve for Micro/Nano-fluidics
This paper describes recent work on a valve to regulate liquid flow in micro/nano-fluidic channels using electrodeposited nanostructures on a solid-state AgGeSe electrolyte. The valve utilizes the extremely rough surface morphology of the electrodeposits to [...]
Nano-Electrodeposits of MEMS Directional Microphones for Hearing Aid Optimization
We present an in-situ non-electronic method for MEMS (Micro-Electro-Mechanical-Systems) microphone optimization by sensitivity adjustment via the growth/retraction of nano-electrodeposits to achieve high directionality in hearing aid applications. Using a DC bias at room temperature, nano-electrodeposits [...]
First self-consistent thermal electron- phonon simulator
We have developed the first self-consistent thermal electron-phonon simulator which solves the Boltzmann transport equation for the electrons and the energy balance equations for phonons, and as such allows us to make realistic estimates on [...]

Zhang Y., Koeneman B.A., Chen Y., Westerhoff P., Capco D.G., Crittenden J., Arizona State University, US
The objective of this research is to evaluate the potential risk of human exposure to nanomaterials in drinking water by examining three issues: 1) characteristics and stability of nanomaterials in the water environment; 2) removal [...]
Adsorption/Desorption of Cd by Titanium Dioxide Nanoparticles and Sediment Particles as well as Their Facilitated Bioaccumulation of Cd into Carp
There are increasing concerns about the health and environmental impact of nanomaterials. The study of Sun et. al 2006 provided the evidence of facilitated bioaccumulation of As(V) in carp in the presence of titanium dioxide [...]
