TL;DR: In this paper, the smallest HfO 2 -based resistive RAM (RRAM) cell was reported, featuring a novel Hf/HfO x resistive element stack, with an area of less than 10×10 nm2, fast ns-range on/off switching times at lowvoltages and with a switching energy per bit of <0.1pJ.
Journal ArticleDOI
Strain-induced semiconductor to metal transition in the two-dimensional honeycomb structure of MoS2
Emilio Scalise,Michel Houssa,Geoffrey Pourtois,Geoffrey Pourtois,Valery V. Afanas'ev,Andre Stesmans +5 more
TL;DR: In this article, the electronic properties of two-dimensional honeycomb structures of molybdenum disulfide (MoS2) subjected to biaxial strain have been investigated using first-principles calculations based on density functional theory.
Journal ArticleDOI
Electronic properties of hydrogenated silicene and germanene
Michel Houssa,Emilio Scalise,Kiroubanand Sankaran,Geoffrey Pourtois,Valeri Afanas'ev,Andre Stesmans +5 more
TL;DR: In this paper, the electronic properties of hydrogenated silicene and germanene, so called silicane and Germanane, respectively, are investigated using first-principles calculations based on density functional theory.
Journal ArticleDOI
Interchain vs. intrachain energy transfer in acceptor-capped conjugated polymers
David Beljonne,Geoffrey Pourtois,Carlos Silva,Emmanuelle Hennebicq,Laura M. Herz,Richard H. Friend,Gregory D. Scholes,Sepas Setayesh,Klaus Müllen,J.L. Brédas +9 more
TL;DR: The calculations indicate a two-step mechanism for intrachain energy transfer with hopping along the conjugated chains as the rate-limiting step; the higher efficiency of the interchain transfer process is mainly due to larger electronic coupling matrix elements between closely lying chains.
Journal ArticleDOI
Bandgap opening in oxygen plasma-treated graphene.
Amirhasan Nourbakhsh,Mirco Cantoro,Tom Vosch,Geoffrey Pourtois,Francesca Clemente,Marleen H. van der Veen,Johan Hofkens,Marc Heyns,Stefan De Gendt,Bert F. Sels +9 more
TL;DR: The opening of a bandgap in graphene is explained in terms of functionalization of its pristine lattice with oxygen atoms, that is, on the extent of the bandgap opening upon increased functionalisation density.
