We study the structure of the electronic states and the transport propertiesof a Kronig-Penney model with weak compositional and structural disorder. Usinga perturbative approach we obtain an analytical expression for the localisationlength which is valid for disorder with arbitrary correlations. We show how togenerate disorder with self- and cross-correlations and we analyse both theknown delocalisation effects of the long-range self-correlations and neweffects produced by cross-correlations. We finally discuss how both kinds ofcorrelations alter the transport properties in Kronig-Penney models of finitesize.
