In a recent combined experimental and theoretical paper, periodic DFT calculations and Bader’s QTAIM analysis explain, at the atomistic level, the enhancement of the performance of MoS2 2D material for the hydrogen evolution reaction (HER),...
In this video tip of the week, Ole demonstrates how easily the work function can be calculated with our periodic DFT code BAND due to the support of true 2D-periodicity. A step-by-step version of the...
A new method of extracting hydrogen from water more efficiently could help underpin the capture of renewable energy in the form of sustainable fuel. Transition metal dichalcogenides are promising electrocatalytic materials for the hydrogen evolution...
Band structures are a widely used tool in solid state physics and materials science to analyze the electronic structure of crystalline materials. However, the band structure of materials relevant for actual applications are often rather...
Whether you are a solid state physicist thinking of chemistry as too arcane or a chemist puzzled by band structure theory: Try out our new tutorial and learn how to neatly link these two fields,...
A periodic extension of the energy decomposition analysis (pEDA) has been implemented in BAND. The natural orbitals for chemical valence (NOCV) is also available – at the gamma-point only. With pEDA researchers can analyze in...
Thomas Heine and coworkers computationally designed a logical junction made from a single material, PdS2. Uniquely, 2D transition metal dichalcogenide PdS2 is semiconducting as a monolayer (ML) while it is semimetallic as a bilayer (BL). By exploiting...
Relativistic periodic DFT calculations show that the band gap of single-layer transition-metal dichalcogenides (MoWSeS) are reduced by high external electric fields. MoS2 and MoSe2 become metallic at fields of 6.5 V Å−1 and 4.5 V...
In Early 2011, researchers Rajeev Ahuja, Andreas Blomqvist and Peter Larsson at Uppsala University along with Pekka Pyykkö and Patryk Zaleski-Ejgierd at the University of Helsinki published the results of an extensive computational study on...
A combined experimental and theoretical study of Bermudez and Robinson (US Naval Research Laboratory) has shown that, although a silica support does not influence the band structure of single-layer graphene, it does influence how water...
