Strain Engineering of Selective Chemical Adsorption on Monolayer MoS_2
Liangzhi Kou, Aijun Du, Changfeng Chen +1
Nanomaterials are prone to influence by chemical adsorption because of their large surface to volume ratios. This enables sensitive detection of adsorbed chemical species which, in…
Charge doping induced phase transitions in hydrogenated and fluorinated graphene
Tim Wehling, Bernhard Grundkötter-Stock, Bálint Aradi +2
We show that charge doping can induce transitions between three distinct adsorbate phases in hydrogenated and fluorinated graphene. By combining ab initio, approximate density func…
Calculation ofthe transitions and migration of nitrogen and vacancy related defects,with implications on the formation of NV centers in bulk diamond
Peter Deák, Bálint Aradi, Moloud Kaviani +2
Formation and excitation energies as well charge transition levels, are determined forthe substitutional nitrogen (Ns),the vacancy (V) and related point defects (NV, NVH, N2, N2V a…
Graphene-based topological insulator with an intrinsic bulk band gap above room temperature
Liangzhi Kou, Binghai Yan, Feiming Hu +5
Topological insulators (TIs) represent a new quantum state of matter characterized by robust gapless states inside the insulating bulk gap. The metallic edge states of a two-dimens…
Proximity Enhanced Quantum Spin Hall State in Graphene
Liangzhi Kou, Feiming Hu, Binghai Yan +4
Graphene is the first model system of two-dimensional topological insulator (TI), also known as quantum spin Hall (QSH) insulator. The QSH effect in graphene, however, has eluded d…
Thermodynamics of quantum coherence
César A. Rodríguez-Rosario, Thomas Frauenheim, Alán Aspuru-Guzik
Quantum decoherence is seen as an undesired source of irreversibility that destroys quantum resources. Quantum coherences seem to be a property that vanishes at thermodynamic equil…
