Aluminium nitride is , a wide-band-gap solid with useful thermal and piezoelectric properties. A common crystal structure is wurtzite.
Its combination of electrical insulation and heat transport supports electronic packaging, while its coupling between strain and electric polarization supports acoustic devices. These properties arise from the bonded lattice rather than from separate aluminium and nitrogen components.
