“…6 ). 87 , 88 The high proportion of defects also leads to advantageous properties such as the ability to take a high loading of dopants and band gap tuning through the number of defect sites. 89 , 90 Although useful, these properties can also lead to compositional differences between nanocrystals of identical size within a batch leading to broadening on the ensemble properties such as the luminescence peak of colloidal nanocrystals.…”

“…4 CSS, therefore, appears to be a good n-type semiconductor when doped, but thus far p-type conductivity has not been realized. This is quite surprising, as CSS would be expected to have a valence band maximum ͑VBM͒ made up of Cu 3d states mixing with S 3p states, which generally results in materials with good p-type semiconducting ability, e.g., Cu 2 S, 7 group 13 I-III-VI 2 materials, 8 and layered oxychalcogenide materials. 9 In this paper we utilize state of the art screened hybrid density functional theory ͑DFT͒ to investigate the stability of CSS in all of the previously reported I-III-VI 2 structures.…”

Cu based I-III-VI 2 materials have received much attention due to their utility in solar cell applications. The vast majority these studies have focused on materials with group IIIA cations as the trivalent metal. In this study we utilize the screened hybrid exchange functional, HSE06, to investigate the stability of CuScS 2 in the crystal structures of all the other I-III-VI 2 materials, and find that it preferentially forms in its own unique structure. We analyze the electronic structure and optical properties of CuScS 2 and in light of this discuss its semiconducting ability.

One of the main requirements for a future Hydrogen Economy is a clean and efficient process for producing hydrogen using renewable energy sources. Hydrogen is a promising energy carrier because of its high energy content and clean combustion. In particular, the production of hydrogen from water and solar energy, i.e., photocatalysis and photoelectrolysis, represent methods for both renewable and sustainable energy production. Here, we will present the principles of photocatalysis and the PhotoElectroChemical cell (PEC cell) for water splitting, along with functional materials. Defect chemical aspects will be high-lighted. To date, the decreasing length scale to the nanoscale of the functional materials attracts widespread attention. The nanostructure is beneficial in case diffusion lengths of the photo-generated charge carriers are substantially different.
