Highlights with ‘BAND’

Screening industrial polymers for lithium–ion batteries electrode materials

Organic polymers are promising electrode materials for lithium ion batteries due to their low solubility, low self-discharge rates, high mechanical strength, great flexibility, superior thermal stability, and versatility. A recent study virtually screens industrial polymers...

Analyzing bonding interactions of molecules on surfaces: Paper & Tutorial

A recent review paper on periodic energy decomposition analysis (pEDA) by Lisa Pecher & Ralf Tonner was widely covered in the media (HLRS, CMFE, EurekAlert). The pEDA calculations enable deep insight in molecule-surface interactions, which...

Understanding Band Structures – “Mirrors of Bonding” in Perovskite Crystals

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...

Perovskite Band Structure & COOP Analysis – Advanced Tutorial

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,...

Promoters in Fischer-Tropsch catalysis

The Fischer-Tropsch reaction aims at synthesizing lower olefins (C2-C4 alkenes) from synthesis gas (CO + H2). In this reaction, typically large amounts of methane are formed as an unwanted side product. In a combined experimental and theoretical study, computational...

Periodic energy decomposition analysis

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...

Closing the band gap in 2D semiconductors

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...

Relativistic effects up the voltage in batteries

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...

Water adsorption on graphene influenced by silica support

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...

BAND calculations explain break-through molecular charge transport experiment

Charge transport through single-molecule junctions is dominated by image charges. This is demonstrated and explained by a combined experimental and theoretical effort from Delft (Quantum Nanoscience and Chemical Engineering departments) and the Leiden Institute of...
