Surface polarization enhancement and switching properties of small ferroelectric particles

Laurent Baudry

We have studied the polarization switching in ferroelectric particles by using a time dependent Ginzburg Landau model. The surface effect is described by considering the polarization enhancement towards the surface. The influence of this phenomena and related bound charges field on switching...

Collective excitations in charged nanocrystals and in close-packed arrays of charged nanocrystals

Christophe Delerue, Guy Allan, Yann-Michel Niquet

We present self-consistent tight binding calculations of the dielectric response of charged semiconductor nanocrystals. We predict collective effects such as the oscillation in opposite phase of the additional electron and of the plasma of valence electrons near the resonance. In arrays of charged...

Reactive ion etching of a 20 nanometers tungsten gate using a SF$_6$/N$_2$ chemistry and hydrogen silsesquioxane hard mask resist

G. Larrieu, Emmanuel Dubois

This article reports on a direct method for patterning a tungsten gate in the decananometric range using high-resolution electron-beam lithography and reactive ion etching (RIE). Electron-beam lithography is based on the use of hydrogen silsesquioxane for its remarkable properties as a negative-...
