The feasibility of fabricating visible-light emitting diodes (VLED\´s) by ion implantation has been investigated. Zn-ions at 20-40 kev energy were implanted into Te-doped GaAs
06P
0.4epitaxial layers on GaAs substrates with ion doses ranging from

to

ions/cm
2. Details of the diode fabrication process will be given, together with the characteristics of the finished devices, as well as resistivity, mobility, and photoluminescence data of the implanted layers as a function of the annealing and implantation parameters.
