Gallium Wikipedia

Gallium reacts with ammonia at 1050 °C to form gallium nitride, GaN. Gallium also forms binary compounds with phosphorus, arsenic, and antimony: gallium phosphide (GaP), gallium arsenide (GaAs), and gallium antimonide (GaSb). These compounds have the same structure as ZnS, and have important semiconducting properties.

Graphene and gallium arsenide: Two perfect partners find ...

In order to make their lower layer of gallium arsenide (plus graphene atomic layer) visible, the PTB physicists chose aluminium arsenide (AlAs). However, it is so similar to gallium arsenide (GaAs) in its optical properties that they had to employ a few tricks: They vapourcoated not only one, but rather several waferthin layers.

Why does Gallium ''melt'' Aluminum? Quora

Gallium doesn''t "melt" aluminum, it amalgamates it much as mercury amalgamates with gold or silver. Aluminum is a soft metal and mercury readily amalgamates with it and as gallium is also a liquid metal it undoubtedly penetrates the crystal structure dissolving the aluminum, too.
