Phonon-assisted tunnelling mechanism of conduction in SnO2 and ZnO nanowires

Ohlckers P., Pipinys P., Vestfold University College, NO

Non-linear temperature-dependent current-voltages characteristics of SnO2 nanowires measured by Ma et al [2005 Solid State Commun 130 313] and single ZnO nanorods from {J.Y. Park et al., 2006 Nanotechnology 17 1255] are explained by the [...]

Advantages and Limitations of Diamond-Like Carbon as a MEMS Thin Film Material

Ohlckers P., Skotheim T., Dmitriev V., Kirpilenko G., Vestfold University College, NO

We can observe from the material properties of Diamond-Like Carbon (DNC) several characteristics can be favourable exploited to make MEMS devices with DNC thin films: Extraordinary yield strength, extraordinary stiffness, high indentation hardness and wear [...]

Compact Modeling Framework for Short-Channel DG and GAA MOSFETs

Børli H., Kolberg S., Fjeldly T.A., Norwegian University of Science and Technology, NO

To achieve sufficient accuracy in the compact modeling of short-channel, nanoscale DG and GAA MOSFETs, the multi-dimensionality of the body potential and the electronic charge distribution has to be accurately described. In sub-threshold, the device [...]

Precise 2D Compact Modeling of Nanoscale DG MOSFETs Based on Conformal Mapping Techniques

Fjeldly T.A., Kolberg S., Norwegian University of Science and Technology, NO

In nanoscale double gate MOSFETs, the dependence on the bias voltages of the 2D electron barrier topology in the conducting channel is all-important for the operation of the device. We consider a DG MOSFET with [...]

Magnetic switch induced electron transport in a double quantum dot

Popsueva V., Førre M., Hansen J.P., University of Bergen, NO

The paper presents a theoretical analysis of controlled singleelectron quantum transport in a two dimensional double quantumdot. The transport is induced by a time dependent magnetic field.From solving the time dependent Schrodinger equation we find [...]

A Method for Adding Static External Forcing to Invariant Manifolds

Grinde C., Westby E.R., Vestfold University College, NO

We present a new method for applying quasi-static forcing to invariant manifolds without breaking its invariance. This is usefull for modeling biased reduced-order models. The results from initial simulations are very promising and examples spesific [...]

Nonlinear Analytical Reduced-Order Models for MEMS

Westby E.R., Fjeldly T.A., Norwegian University of Science and Technology, NO

We present a method for constructing a nonlinear, analytical, reduced-order model for MEMS-structures. The method is based on the center manifold approach for describing nonlinear modes of mechanical systems, in combination with techniques for predicting [...]
