Les travaux effectu\u00e9s par une \u00e9quipe de quatre professeurs (Thomas Szkopek, Guillaume Gervais, Richard Martel et Mohamed Siaj<\/a>), inter-disciplinaire (chimie, physique, g\u00e9nie \u00e9lectrique), inter-universitaire (McGill, UdeM, UQAM<\/a>), et \u00e9galement inter-regroupementaire (RQMP\/CQMF) viennent d’\u00eatre publi\u00e9s dans le journal Physical Review Letters<\/a>.<\/p>\n

Ces travaux concernent les r\u00e9sultats de leur \u00e9tude sur l’effet Hall quantique dans graph\u00e8ne hydrog\u00e9n\u00e9.<\/p>\n<\/div>

Effet Hall quantique dans le graph\u00e8ne hydrog\u00e9n\u00e9:<\/strong> L’effet Hall quantique est observ\u00e9 dans un gaz d’\u00e9lectrons bidimensionnel form\u00e9 dans du graph\u00e8ne hydrog\u00e9n\u00e9 \u00e0 l’\u00e9chelle millim\u00e9trique, avec une mobilit\u00e9 inf\u00e9rieure \u00e0 10 cm2 \/ V \u00b7 s et le param\u00e8tre de trouble Ioffe-Regel correspondant (kF\u03bb) – 1\u226b1. Dans un champ magn\u00e9tique nul et \u00e0 basse temp\u00e9rature, le graph\u00e8ne hydrog\u00e9n\u00e9 est isolant avec une r\u00e9sistance en deux points de l’ordre de 250h \/ e2. L’application d’un champ magn\u00e9tique puissant g\u00e9n\u00e8re une magn\u00e9tor\u00e9sistance colossale n\u00e9gative, avec une r\u00e9sistance \u00e0 deux points saturant \u00e0 moins de 0,5% de h \/ 2e2 \u00e0 45 T. Nos observations sont coh\u00e9rentes avec l’ouverture d’un espace induit par des impuret\u00e9s dans la densit\u00e9 des \u00e9tats de graph\u00e8ne. L’interaction entre la localisation d’\u00e9lectrons par diffusion de d\u00e9fauts et le confinement magn\u00e9tique dans les cristaux atomiques bidimensionnels est discut\u00e9e.<\/p>\n
