There are a few rare exceptions for solids that are considered minerals and have an amorphous (non-crystalline) structure. One way they can form is through rapid cooling which means they don’t ...

An amorphous material is one that may have short range atomic order but that lacks the translational symmetry (long range order) of a crystalline solid. Glasses are an example of amorphous materials ...

As is well known, amorphous materials typically have lower density than crystalline phases. As a result, the change in shape and volume for an applied load is anticipated to be greater for ...

A semiconductor that uses a silicon or gallium arsenide substrate composed of a single crystal. Its atomic structure is the same throughout the material. Contrast with amorphous semiconductor.

It should be noted however, that with both the semi crystalline and amorphous materials at sufficiently high temperature (this is when the material is in its melt state) the molecular structure is ...

Amorphous metals, also known as metallic glasses, are metallic materials that have a non-crystalline structure. Most amorphous metals are alloys rather than pure metals. These materials have atoms of ...
