Nous avons mesuré à la fois la chaleur spécifique, la pression gazeuse et la résistivité thermique afin de préciser la formation des couches et le début de la superfluidité sur un substrat de graphite UCAR-ZYX d'une très grande uniformité. Nous avons observé des maxima très marqués de chaleur spécifique dus à la désorption d'une couche lors d'une augmentation de température. Ces maxima permettent de déterminer le remplissage de chaque couche ainsi qu'une détermination précise du nombre de couches pour nos mesures de résistivité thermique. Lorsque le nombre de couches absorbées dépasse cinq, on peut observer des amorces de superfluidité et des flaques tridimensionelles qui sont compatibles avec les modèles de "percolation".We have combined h...
