Improvement of current-control induced by oxide crenel in very short field-effect-transistor

A 2D quantum ballistic transport model based on the non-equilibrium Green's function formalism has been used to theoretically investigate the effects induced by an oxide crenel in a very short (7 nm) thin-film metal-oxide-semiconductor-field-effect-transistor. Our investigation shows that a well adjusted crenel permits an improvement of on-off current ratio Ion/Ioff of about 244% with no detrimental change in the drive current Ion. This remarkable result is explained by a nontrivial influence of crenel on conduction band-structure in thin-film. Therefore a well optimized crenel seems to be a good solution to have a much better control of short channel effects in transistor where the transport has a strong quantum behavior

Activation is not a panacea: active labour market policy, long-term unemployment and institutional complementarity

Evaluation studies of active labour market policy show different activation measures generate contradictory results. In the present study, we argue that these contradictory results are due to the fact that the outcomes of activation measures depend on other institutions. The outcome measure in this study is the long-term unemployment rate. Two labour market institutions are of special interest in this context: namely, employment protection and unemployment benefits. Both institutions, depending on their design, may either increase or decrease the effectiveness of active labour market policies in lowering long-term unemployment. Based on an analysis of macro-level data o
