Hi,
I found buying an anatase TiO2 thin film (around 100 nm and 200 nm) deposited on silicon.
If anyone have information, please tell me what you know.
Best regards.

Is it possible that Brustein-Moss effect causes the increase of band-gap of p-type semi-conductor? Thanks. Best regards.

Hi! In function of temperature, the lattice constant were modified. I want to rely this modification to the redshift of bandgap energy of ZnO. Can you help me !!! Best regards. Bouzouraa Montassar.
