Potassium chloride (KCl) is a type of salt that is commonly used as a substrate in various scientific and industrial applications. In the context of electronics, KCl is used as a substrate material for the growth of various crystalline compounds, such as II-VI semiconductors and metal oxides.
KCl has several properties that make it an attractive substrate material. For example, it has a low thermal expansion coefficient, which makes it suitable for use in temperature-sensitive applications. Additionally, KCl has a large bandgap and high dielectric constant, which make it a suitable substrate for the growth of high-k dielectric materials.
In the field of optoelectronics, KCl is used as a substrate for the growth of semiconductor materials, such as CdTe and CdS. These materials are commonly used in solar cells, light-emitting diodes, and other optoelectronic devices.
