# Volume V — Crystals and Surfaces

From the isolated molecules and clusters of the earlier volumes to **extended matter**:
periodic crystals and the surfaces where they meet the world. The total energy of a
solid, computed as a function of its cell, fixes its **lattice constants** and its
**bulk modulus** through an equation of state; the energy of a molecule sitting on a
slab fixes its **adsorption energy**, the central quantity of heterogeneous catalysis.
These notebooks work from the course's own calculations, run with the Atomic
Simulation Environment.

```{admonition} Source lectures
:class: note
This volume develops **Lecture 1** of *Molecular and Materials Modelling*
(FS 2023) — *the Atomic Simulation Environment and the equation of state* — and
**Lecture 8** — *adsorption and dispersion on metal surfaces*. Each notebook
repeats its specific lecture provenance in its overview; the full lecture map is
in `manifest.yml`.
