摘要
A method for the low-temperature production of radial electronic junction semiconductor nanostructures on a substrate, includes: a) forming on the substrate, metal aggregates capable of electronically doping a first semiconductor material; b) growing, in the vapor phase, doped semiconductor nanowires in the presence of one or more non-dopant precursor gases of the first semiconductor material, the substrate being heated to a temperature at which the metal aggregates are in the liquid phase, the growth of the doped semiconductor nanowires in the vapor phase being catalyzed by the metal aggregates; c) rendering the residual metal aggregates inactive; and d) the chemical vapor deposition, in the presence of one or more precursor gases and a dopant gas, of at least one thin film of a second semiconductor material so as to form at least one radial electronic junction nanostructure between the nanowire and the at least one doped thin film.
