A review. Ab initio mol. dynamics (MD) allows realistic simulations to be performed without adjustable parameters. In recent years, the technique has been used on an increasing no. of applications to biochem. systems. Here we describe the principles on whi ...
This paper presents a new Procedural Analog Design tool called PAD. It is a chart-based design environment dedicated to the design of analog circuits aiming to optimise design and quality by finding good tradeoffs. This interactive tool allows step-by-step ...
Active feedback stabilization of the vertical instability is studied for highly elongated tokamak plasmas (2 less-than-or-equal-to kappa less-than-or-equal-to 3) and evaluated in particular for the TCV configuration. It is shown that the feedback can stron ...
Reliable split C(V) measurements are shown to be feasible on ultra-thin oxides (down to 1.2 nm) by using relatively small area MOSFETs (typically 100 mum(2)). To this end, specific correction procedures for parasitic parallel capacitances and gate leakage ...
We present experimental transport characteristics of long and ballistic superconductor - 2-dimensional electron gas - superconductor junctions obtained in a temperature range from 1K down to 10mK. Surprisingly the critical current I-c can be fitted to the ...
Fault current limiters (FCLs) can be considered as key elements in power systems using high temperature superconductors. This analysis takes into account the system benefits provided by the introduction of FCLs in various network configurations. New meshin ...
The authors have demonstrated the operation of a simple optical bolometer by irradiating a constriction in a Y1Ba2Cu3O7-δ thin film with chopped laser light at λ=633 nm. The change in film resistivity was measured by lock-in detection of the AC component i ...
In this letter, we present normally-off GaN-on-Si MOSFETs based on the combination of tri-gate with a short barrier recess to yield a large positive threshold voltage (VTH), while maintaining a low specific on resistance (RON,SP) and high current density ( ...
Today's world of electronics becomes more and more digital and therefore CMOS becomes the dominant technology. A CMOS process compared to a bipolar process offers several advantages, mainly a low power consumption which is important for portable systems po ...
