Optical, electrical and structural properties of AlN thin films

AlMoN based spectrally selective coating with improved thermal stability for high temperature solar thermal applications

“…Aluminum molybdenum nitride based coating has been chosen for high temperature solar thermal applications, because both aluminum and molybdenum nitride coating exhibits good optical properties (i.e., low reflectance in the visible region) (Zhu and Tan, 1995). In addition, AlN coating exhibits high decomposition temperature (2490°C), chemical stability (in air up to 700°C), refractive index (1.9-2.1) and good dielectric properties (Morosanu et al, 1995). Further, it is expected that a combination of MoN and AlN will improve the optical properties and thermal stability of AlMoN coatings.…”
