Cetineites: Electronic, optical, and conduction properties of nanoporous chalcogenoantimonates

The electronic, optical, and conduction properties of the cetineites, a new ly discovered class of crystalline nanoporous materials, have been calculat ed within a full-potential framework using the augmented Fourier components technique in combination with the extended linear augmented plane-wave k.p method. Photoemission, optical, and conductivity measurements have been pe rformed and the calculated results are in conclusive agreement with all ava ilable experimental data. This helps in understanding the semiconducting na ture of the cetineites, which is an exceptional property for nanoporous cry stals.
