Density of States

Source: src/lib/electronic/DosPlot.svelte, src/lib/electronic/DosAnalysisPane.svelte

Overview

The DOS module visualizes total and projected density of states from DFT calculations. Supports atom-resolved and orbital-resolved projections.

Components

DosPlot

Interactive DOS plotting component.

DosAnalysisPane

Analysis controls for DOS data.

DosPlotWindow

Standalone DOS viewer window.

Data Format

• energies — Energy grid relative to Fermi level
• total_dos — Total DOS values
• pdos — Projected DOS by atom and orbital
• spin — Spin channel (up/down for spin-polarized)

Features

Projection Types

• Total DOS
• Atom-projected DOS
• Orbital-projected DOS (s, p, d, f)
• Element-projected DOS

Integration

Interactive integration over energy ranges to compute electron counts.
