Abstract :
Optically active and electrically excitable silicon pillar structure is fabricated by electrochemical etching method. Silicon pillars structure is made by etching porous silicon layers in hydrofluoric acid-based solution. Afterwards, silicon pillars that are spin-coated with Er silicate show strong Er-related 1.53 mum photo luminescence.
