We report direct first-principles density-functional calculations of the piezoelectric tensor d⇊ relating polarization to applied stress for the binary compounds AlN, GaN, and InN. The values of d⇊ are rather sensitive to the choice of the exchange-correlation functional, and results are presented for both the local-density and gradient approximations. A comparison with experiment and with values predicted indirectly from the elastic C⇊ and piezoconstant e⇊ tensors is also presented.
