Abstract (en)

[origin: WO2018091502A1] Process for fabricating a heterostructure made of semiconductor materials having a crystalline structure of wurtzite type, comprising the following steps: - structuring a surface (SD) of a zinc oxide monocrystalline substrate (S) into mesas (M); - depositing by epitaxy at least one layer (CA) of semiconductor materials having a crystalline structure of wurtzite type, forming said heterostructure, on top of the structured surface. Heterostructure obtained by such a process. Process for fabricating at least one electronic or optoelectronic device from such a heterostructure.
