General description
Ammonium sulfide solution (aqueous ammonium sulfide) is a 40-48wt.% solution in water. Ammonium sulfide is an inorganic salt with a sulfurous odor, which is commonly used in the food industry as a flavoring agent. The influence of ammonium sulfide treatment on (100)GaAs (gallium arsenide) surfaces has been studied by x-ray photoelectron spectroscopy (XPS) and reflection high-energy electron diffraction (RHEED). Its potential as an alternative to hydrogen sulfide for the transformation of activated amides to thioamides by thiolysis has been investigated. The reaction of ammonium sulfide with 3-hydroxy-2-butanone over a range of temperature has been reported to form various flavor compounds.
Application
Ammonium sulfide solution may be used to enhance the performance of type-II InAs/GaSb super lattice photodiodes by surface passivation technique.
