Brief description

The database includes one-dimensional materials with structural, thermodynamic, electronic, magnetic, and optical properties. The materials are studied in bulk as well as as isolated one-dimensional components. Density functional theory (DFT), as implemented in the GPAW electronic structure code, is used to calculate the properties. The Atomic Simulation Recipes (ASR) were used to create the workflow, which was then performed using the MyQueue task management. Below you’ll find the process script as well as a table with the numerical parameters used to calculate the various attributes.
