General description

Aluminum nitride (AlN) is a wide bandgap semiconductor with exceptional thermal conductivity, high electrical insulation, and piezoelectric properties. It is widely used in electronics, such as in high-power and high-frequency devices, as well as in optoelectronics for UV light emitters. Additionally, AlN is utilized in biomedical devices due to its biocompatibility.

Application

  • This review explores the significant properties of aluminum nitride in the context of semiconductor materials, discussing its large bandgap and wide transparency range, which are advantageous for ultraviolet to mid-infrared applications (Li et al., 2021).

Nanocomposites consisting of cellulose nanofibrils (CNFs) and nano-aluminum nitride (AlN) were prepared using a simple vacuum-assisted filtration process. Bleached sugarcane bagasse pulp was treated with potassium hydroxide and sodium chlorite, and was subsequently ultra-finely ground and homogenized to obtain CNFs.
