2014 Nous étudions les effets dûs à la coexistence de l’ordre cristallin (ou hexatique) et des fluctuations thermiques dans les membranes à tension superficielle négligeable. Si la connectivité de l’état cristallin est parfaite, la membrane n’est pas plissée à basse température. Si l’on permet la formation de dislocations, l’écrantage des contraintes élastiques dû au flambage produit une concentration diluée de dislocations libres à toute température non nulle. Si la phase hexatique qui en résulte est stable, la rigidité associée aux corrélations orientationnelles produit une augmentation logarithmique de la rigidité de courbure qui s’oppose à la diminution produite par les fluctuations thermiques que l’on trouve dans les membranes fluides....
