The description of the relative positions of the points within a unit cell is called a basis. Mathematical Definition In the three-dimensional space $\mathbb{R}^{3}$, for a given lattice $L = \left\{ n_{1}\mathbf{a}_{1} + n_{2}\mathbf{a}_{2} + n_{3}\mathbf{a}_{3} \mid n_{i} \in \mathbb{Z} \right\}$, lethttps://freshrimpsushi.github.io/en/posts/3786/Thu, 26 Feb 2026 00:00:00 +0000https://freshrimpsushi.github.io/en/posts/3786/Description Materials Project (MP) is an open-source database for inorganic materials. Using the MP API client, you can conveniently access and query the MP database from Python. Finding by id First, you need your API Key, so sign up before proceeding. You can pass desired material ids or property-based conditions as inputs to mpr.materials.summary.search() to retrieve data. For example, the following code retrieves summary information for the materials mp-2209 andhttps://freshrimpsushi.github.io/en/posts/3751/Thu, 18 Dec 2025 00:00:00 +0000https://freshrimpsushi.github.io/en/posts/3751/Description Materials Project (MP) is an open-source database for materials science researchers. It provides computational data for various inorganic materials and offers a Python-based API for convenient access. The following description refers to the official documentation; for details not included here, please consult the official documentation. Signing up and obtaining an API Key To use the MP API, you must sign up on the MP website.

Mathematical definition linearly independent $3$dimensional vectors $\mathbf{a}_{1} \in \mathbb{R}^{3}$ ($i = 1, 2, 3$). For these, the set of all points that are integer-coefficient linear combinations of them is called a lattice. $$ \text{Lattice} := \left\{ n_{1} \mathbf{a}_{1} + n_{2} \mathbf{a}_{2} + n_{3} \mathbf{a}_{3} \mid n_{1}, n_{2}, n_{3} \in \mathbb{Z} \right\}
