Yes, there is an essential difference between gallium arsenide and arsenic. Arsenic is a simple substance and a toxic substance, while gallium arsenide is a compound whose properties are completely different from arsenic. Gallium arsenide is an excellent ?semiconductor material.
About Gallium:
Gallium is perfectly safe to handle since it is non-toxic to humans.The only thing is that gallium sticks to things when liquid and it amalgamates with other metals, destroying them. Gallium metal is safe. You can probably eat it, but don't eat it. Gallium is much safer than mercury.
Gallium exposure can cause several problems, from pure cosmetics to ruining your day. Because gallium is at 30 º The temperature of human skin is about 30 ℃. So it should be assumed that every time people come into contact with gallium, a certain amount of liquid metal is transferred to the body. Because the boiling point of gallium is so high, the metal will stay on the body, contaminate it and transfer to any surface that comes into contact with it.
The chemical formula of gallium arsenide is GaAs. Black gray solid, melting point 1238 ℃. It is stable in air below 600 ℃ and is not eroded by non oxidizing acid. Gallium arsenide can be used as semiconductor material, and its performance is better than that of silicon. It has large band gap, high electron mobility, small dielectric constant, can introduce deep level impurities, small electron effective mass, special energy band structure and dual Valley conduction band. It can be used to fabricate light-emitting devices, semiconductor lasers, microwave bulk effect devices, solar cells and high-speed integrated circuits, etc. it is widely used in radar, electronic computers, artificial satellites, etc Spacecraft and other cutting-edge technology.
In terms of its chemical properties, the human body is an oxidized weak alkaline substance, which will not be eroded. It is very stable and does not need to care too much.
