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).
