Au fur et à mesure que les composants électroniques se miniaturisent, des limites apparaissent en terme de puissance dissipée et de l’échauffement qui en résulte. Le problème se pose notamment pour les transistors à effet de champ. Le phénomène de capacité négative de ferroélectriques suscite beaucoup d’intérêt car il apparaît comme une solution potentielle pour réduire la consommation de l’énergie des transistors à effet de champ. La stabilisation de ce régime de capacité négative est attendue dans le matériau ferroélectrique lorsqu’il est associé en série à un paraélectrique au sein d’une hétérostructure. Les super-réseaux ferroélectriques / paraélectriques constituent des systèmes modèles pour étudier le phénomène de capacité négative. N...
