All the article says is "a new material made from indium arsenide and aluminum".

> Fermions have a half-odd-integer spin (spin 1/2 , spin 3/2 , etc.) and obey the Pauli exclusion principle.
> These particles include all quarks and leptons and all composite particles made of an odd number of these, such as all baryons and many atoms and nuclei
I this it's a way to describe a set of particles or "objects" with certain properties.
