SPIN: [S]imple [P]ython [I]pywidgets [N]otebook interface to obtain the optoelectronic properties of materials employing DFT

Abstract

The Simple Python Ipywidgets Notebook interface to obtain the optoelectronic properties of materials (SPIN) is an open source graphical user interface that allows users to work with standard SIESTA files and perform end-to-end atomic level simulation processes. It contains the complete flow, from the construction and visualization of structures or systems until the pre-processing, execution, and post-processing of calculations such as structure optimization, electronic properties like band structure, density of states (DOS), and optical properties. SPIN is an easy-to-use and fast-learning solution written in Python and built from Ipywidgets. However, the end-user can use all available features without the need for Python language knowledge.

SPIN is an Ipywidgets based Interface that allow users to work easily in any operating system (Windows, Linux and Mac), because it works on Jupyter Notebooks.
