Structural and Optical Properties of Aluminum Nitride …

Aluminum nitride thin films were deposited on Si (100) substrate by pulsed DC (asymmetric bipolar) reactive magnetron sputtering under variable nitrogen flow in a gas mixture of argon and nitrogen. The deposited film was characterized by grazing incidence X-ray diffraction (GIXRD), atomic force microscope (AFM), spectroscopic ellipsometry, and secondary ion mass spectroscopy (SIMS).

Preparation and properties of AlN (aluminum nitride ...

The aluminum nitride (AlN) powder/thin films were prepared from an aluminum–urea complex. The complex, hexa urea aluminate(III) chloride, has proven to be a potential single source precursor to aluminum nitrides because urea molecules construct a coordination sphere around the metal atom and form a stable structure, compared with air sensitive halide and hydride precursors.
