چکیده

Transition metal dichalcogenide (TMD) MoS2 and WS2 monolayers (MLs) deposited atop of crystalline zinc oxide (ZnO) graphene-like ZnO (g-ZnO) substrates have been investigated by means density functional theory (DFT) using PBE GLLBSC exchange-correlation functionals. In this work, the electronic structure optical properties studied hybrid nanomaterials are described in view influence thickness on MoS2@ZnO WS2@ZnO two-dimensional (2D) nanocomposites. The thicker substrate not only triggers decrease imaginary part dielectric function relatively to more thinner g-ZnO but also results less accumulated charge vicinity Mo W atoms at conduction band minimum. Based our calculations, we predict that placed yield essential enhancement photoabsorption visible region solar spectra and, thus, can be used as a promising catalyst for photo-driven water splitting applications.

Relativistic Pseudopotential Calculations for Electronic Excited States

Relativistic and electron correlation effects play a important role in the electronic structure of molecules containing heavy elements (main group elements, transition metals, lanthanide and actinide complexes). It is therefore mandatory to account for them in quantum mechanical methods used in theoretical chemistry, when investigating for instance the properties of heavy atoms and molecules in...

Quantum Monte Carlo Calculations for Ground and Excited States

A brief overview of the diffusion quantum Monte Carlo method is given. We illustrate the application to ground-state calculations by a study of the relative stability of carbon clusters near the crossover to fullerene stability, thereby determining the smallest stable fullerene. The application to excited states is illustrated via a study of excitonic states in small hydrogenated silicon cluste...

2. To make a sample chamber, center the small coverslip on the large coverslip and separate them with narrow strips of 30-μm-thick Mylar R © A film parallel to the long edges of the large coverslip. With the two coverslips clamped together (e.g., with binder clips), use UV-curing Norland Optical Adhesive 61 and a UV lamp to seal the two edges of the small coverslip parallel to the spacers. We f...
