Abstract
We present an analysis of the ionicity factor as a function of hydrost atic pressure for GaP, GaAs, InP and InAs. This factor has been calcul ated by means of our recent model. We show that the structural phase t ransition, habitually predicted by a classical calculation of the tota l energy, can be easily seen from the behaviour of the bonding charact er. The results are compared with the experimental data with reasonabl e agreement. Copyright (C) 1996 Elsevier Science Ltd
