We have achieved growth of ZnO nano-columns (NCs) on porous silicon (PS)/Si(111) substrates, using commercial Zn powder by thermal evaporation in an atmosphere. Samples are annealed in wet oxygen and ambient argon gases of argon (Ar) gas. Structural and optical characterizations were performed using scanning electron microscopy (SEM), high resolution X-ray diffraction (HR-XRD) and photoluminescence (PL) spectroscopy. The obtained results of ZnO NCs indicated that the ZnO NCs on PS/ Si (111) substrates were of quite well-ordered and of good quality because the lattice mismatch between the ZnO NCs and substrates is small as compared to growth on some other substrates..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
