Annotation This paper presents experimental results demonstrating the influence of the doping level of InP on the porous layer formation on its surface during the electrochemical etching. It is established that the more high-quality porous layers are formed using the crystals with the free carrier concentration of 2,3 × 1018 cm–3. The observation results of InP layered heterogeneity are discussed and explained in terms of the features of the growing process of heavily doped crystals.
