Ga 2 S 3 decomposes at high temperature forming the non-stoichiometric sulfide, Ga 4 S x (4.8 < x < 5.2). [5] Ga 2 S 3 dissolves in aqueous acids and decomposes slowly in moist air forming H 2 S. [2] Ga 2 S 3 dissolves in aqueous solutions of potassium sulfide, K 2 S to form K 8 Ga 4 S 10 containing the (Ga 4 S 10) 8− anion which has an ...
Gallium(II) sulfide, GaS, is a chemical compound of gallium and sulfur. The normal form of gallium(II) sulfide as made from the elements has a hexagonal layer structure containing Ga 2 4+ units which have a Ga-Ga distance of 248pm. [ 1 ]
3 with elemental gallium in vacuum at 500 °C to 700 °C yields the dark brown gallium(I) oxide, Ga 2 O. [3]: 285 Ga 2 O is a very strong reducing agent, capable of reducing H 2 SO 4 to H 2 S. [3]: 207 It disproportionates at 800 °C back to gallium and Ga 2 O 3. [7] Gallium(III) sulfide, Ga 2 S 3, has 3 possible crystal modifications.

Gallium(III) sulfide, Ga 2 S 3, has 3 possible crystal modifications. [37]: 104 It can be made by the reaction of gallium with hydrogen sulfide (H 2 S) at 950 °C. [33]: 162 Alternatively, Ga(OH) 3 can be used at 747 °C: [38] 2 Ga(OH) 3 + 3 H 2 S → Ga 2 S 3 + 6 H 2 O. Reacting a mixture of alkali metal carbonates and Ga 2 O 3 with H

Charge carrier density, also known as carrier concentration, denotes the number of charge carriers per volume. In SI units, it is measured in m −3. As with any density, in principle it can depend on position. However, usually carrier concentration is given as a single number, and represents the average carrier density over the whole material.
