semiconductors and on the deposition of metallic and semiconductor materials into micropores. Preparation of high
quality lattice mismatched epitaxial layers is one of the most challenging tasks in semiconductor technology.
Electrochemically prepared micro and nanopores in InP and GaAs will be overgrown by LPE and MOCVD to evaluate (i)
the conversion of pores into microbubbles and microlamellae, (ii) the expected reduction of dislocation density
in the overgown layer, (iii) the strain distribution at heterointerfaces. Remote plasma CVD and electrochemical
deposition will be used to deposit ZnO into micropores and onto porous GaP substrates to study the unique optical
properties of these structures. Pt will be deposited electrochemically into porous networks as the first step
towards the preparation of metamaterials. Structural, electrical, and optical properties will be investigated
by optical microscopy, SEM, AFM, SIMS, wet etching, Hall measurement, PL, and microCL.
