Corner Effect and Local Volume Inversion in SiNW FETs

Mihai Adrian Ionescu, Kirsten Emilie Moselund, Luca De Michielis, Luca Selmi

In this paper, a quantitative study of the corner effect and of the local volume inversion on gate-all-around MOSFETs based on numerical simulations has been carried out; different angles and doping levels are compared, in order to understand the impact of ...

Indecomposable Coverings with Concave Polygons

Doemoetoer Palvoelgyi

We show that for any concave polygon that has no parallel sides and for any k, there is a k-fold covering of some point set by the translates of this polygon that cannot be decomposed into two coverings. Moreover, we give a complete classification of open ...

Decomposition of Geometric Set Systems and Graphs

Doemoetoer Palvoelgyi

We study two decomposition problems in combinatorial geometry. The first part of the thesis deals with the decomposition of multiple coverings of the plane. We say that a planar set is cover-decomposable if there is a constant m such that any m-fold coveri ...

Grazing function g and collimation angular acceptance

Valentina Previtali

The grazing function g is introduced—a synchrobetatron optical quantity that is analogous (and closely connected) to the Twiss and dispersion functions β, α, η, and η′. It parametrizes the rate of change of total angle with respect to synchrotron amplitude ...

Spectromètre pour l'étude des réactions (n, a) à 14 MeV

Jean-François Loude

A spectrometer has been constructed for the study of (n, α) reactions at 14 MeV, By detecting the 4He particle associated with neutron production, it is possible to measure the a time-of-flight in addition to the residual energy and energy loss, as measure ...
