Abstract

The electronic device comprises a substrate (1), at least one semiconductor nanowire (2) and a buffer layer (3) interposed between the substrate (1) and said nanowire (2). The buffer layer (3) is at least partly formed by a transition metal nitride layer (9) from which extends the nanowire (2), said transition metal nitride being chosen from: vanadium nitride, chromium nitride, zirconium nitride, niobium nitride, molybdenum nitride, hafnium nitride or tantalum nitride.
