Electronic and Optical Behaviors of Platinum (Pt) Nanoparticles and Correlations with Gamma Radiation Dose and Precursor Concentration

Nanomaterials
The purpose of this research is to examine how the electro-optical behavior of platinum (Pt) nanoparticles prepared via the gamma radiolysis process is related to both the radiation dose and to the Pt precursor concentration.

First-Principles Study on Influences of Crystal Structure and Orientation on Band Offsets at the CdS/Cu2ZnSnS4 Interface

International Journal of Photoenergy, 2012
Cu2ZnSnS4 (CZTS) has attracted much attention recently as an absorber layer material in a heterojunction solar cell. Using the first-principles method, we calculate the band offsets for the CdS/CZTS heterojunction.

Tuning the rear conduction band offset in CIGS thin-film solar cells using Sb2(S1−xSex)3 electron blocking layer to improve efficiency

Results in Physics
The integration of an electron blocking layer (EBL) is a promising strategy to enhance the open-circuit voltage (Voc) and efficiency of CIGS (Cu(In,Ga)Se2) solar cells.

Dirac Cones, Topological Edge States, and Nontrivial Flat Bands in Two-Dimensional Semiconductors with a Honeycomb Nanogeometry

Physical Review X, 2014
We study theoretically two-dimensional single-crystalline sheets of semiconductors that form a honeycomb lattice with a period below 10 nm. These systems could combine the usual semiconductor properties with Dirac bands.

Tuning optical properties of transparent conducting barium stannate by dimensional reduction

APL Materials, 2015
We report calculations of the electronic structure and optical properties of doped n-type perovskite BaSnO3 and layered perovskites. While doped BaSnO3 retains its transparency for energies below the valence to conduction band onset, the doped layered ...
