The second objective is a full understanding of the VCPD results combined with a description of the principal factors that affect KPFM measurements with the application of Kelvin probe (KP) numerical modelling. This enables the

Also, we showed that the observed potential profile along the cleaved surface of the n-InP/InP:nid/p-InP:Zn
