硫化铵溶液（硫化铵水溶液）是 17% 的水溶液。 硫化铵是一种有硫磺臭味的无机盐，在食品工业中常用作调味剂。用 X 射线光电子能谱 (XPS) 和反射高能电子衍射 (RHEED) 研究了硫化铵处理对 (100) GaAs（砷化镓）表面的影响。 已经研究了其作为硫化氢的替代物用于通过硫解将活化的酰胺转化为硫代酰胺的潜力。硫化铵与 3-羟基-2-丁酮在一定温度范围内反应生成不同的风味化合物。硫化铵溶液可通过表面钝化技术提高 Ⅱ 型 InAs/GaSb 超晶格光电二极管的性能 Ammonium sulfide solution (aqueous ammonium sulfide) is a 17% 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. Ammonium sulfide solution may be used to enhance the performance of type-II InAs/GaSb super lattice photodiodes by surface passivation technique
