Superior Hardness and Stiffness of Diamond Nanoparticles
Alexander Quandt, Igor Popov, David Tománek
We introduce a computational approach to estimate the hardness and stiffness of diamond surfaces and nanoparticles by studying their elastic response to atomic nanoindentation. Res…
Reducing sheet resistance of self-assembled transparent graphene films by defect patching and doping with UV/ozone treatment
Tijana Tomašević-Ilić, Djordje Jovanović, Igor Popov +4
Liquid phase exfoliation followed by Langmuir-Blodgett self-assembly (LBSA) is a promising method for scalable production of thin graphene films for transparent conductor applicati…
Pyramids and cootie catchers: new massless fermions in 2D materials
Vladimir Damljanovic, Rados Gajic, Igor Popov
Dirac-like electronic states are the main engines powering the tremendous advances in research of graphene, topological insulators and other materials with these states. Zero effec…
Proximity induced topological state in graphene
Igor Popov, Mauro Mantega, Awadhesh Narayan +1
The appearance of topologically protected states at the surface of an ordinary insulator is a rare occurrence and to date only a handful of materials are known for having this prop…
Magnetism and Antiferroelectricity in MgB
Igor Popov, Nadjib Baadji, Stefano Sanvito
We report on a density functional theory study demonstrating the coexistence of weak ferromagnetism and antiferroelectricity in boron-deficient MgB6. A boron vacancy produces an al…
Designing electrical contacts to MoS monolayers: A computational study
Igor Popov, Gotthard Seifert, David Tománek
Studying the reason, why single-layer molybdenum disulfide (MoS) appears to fall short of its promising potential in flexible nanoelectronics, we found that the nature of conta…
New route for stabilization of 1T-WS2 and MoS2 phases
Andrey N. Enyashin, Lena Yadgarov, Lothar Houben +5
The phenomenon of a partial 2H\rightarrow1T phase transition within multiwalled WS2 nanotubes under substitutional Rhenium doping is discovered by means of high-resolution transmis…
