چکیده

Although self-assembled quantum dots are grown on wetting layers, most simulations exclude the wetting layer. The neglected effects on the electronic structure of a pyramidal InAs quantum dot embedded in a GaAs matrix are investigated based on the effective one electronic band Hamiltonian, the energy and position dependent electron effective mass approximation, and a finite height hard-wall 3D confinement potential.

A Facile Solvothermal Method for Synthesis of CuInS2 Nanostructures

CuInS2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  In  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. The effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  The nanostructures  were  characterized  by  means ...

Theoretical maximum efficiency of solar energy conversion in plasmonic metal-semiconductor heterojunctions.

Plasmonics can enhance solar energy conversion in semiconductors by light trapping, hot electron transfer, and plasmon-induced resonance energy transfer (PIRET). The multifaceted response of the plasmon and multiple interaction pathways with the semiconductor makes optimization challenging, hindering design of efficient plasmonic architectures. Therefore, in this paper we use a density matrix m...

ZSM-5 Zeolite As Host Material for Semiconductor Nanoparticles

This work describes the optical and structure properties of nickel sulfide and cobalt sulfide nanoparticles in ZSM-5 zeolite. The samples were obtained by sulfidation of the Ni2+ and Co2+ ion-exchange ZSM-5 zeolites in a Na2S solution at room temperature. The optical properties of the samples were studied by UV-visible spectroscopy. Their crystalline structure and morphology were studied by X-r...
