NaCl Sodium Chloride Crystal Substrates
Sodium Chloride (NaCl) Crystal Substrates
NaCl single crystal substrates are commonly used as substrate materials for expitaxial thin film growth. NaCl is hygroscopic by nature and very sensitive to moisture. NaCl crystal substrates must be stored in desiccator container to avoid hydration.
