The photoelectrochemical behavior of n-ZnO, n-CdS, and n-GaP single crystal semiconductor electrodes was investigated in acetonitrile which contained various electroactive compounds whose standard redox potential varied by over 3.2 V. The cyclic voltammograms of the n-type semiconductors in the dark and illuminated were compared to the Nernstian behavior at a Pt disk electrode. The photodissolu...

Carbon quantum dots (CDs) are a new class of fluorescent carbonaceous nanomaterials that were casually discovered in 2004. Since then, they have become object great interest the scientific community because their peculiar optical properties (e.g., size-dependent and excitation wavelength-dependent fluorescence), which make them very similar to well-known semiconductor suitable for application p...

Ligand-induced chirality in colloidal semiconductor nanocrystals attracts attention because of their tunable chiroptical properties. Here, the induced and circularly polarized luminescence (CPL) are investigated as a function CdS shell growth range 2D CdSe/CdS nanoplatelets (NPLs) capped with chiral ligands. Five samples NPLs synthesized by one-pot approach to vary island-like on four-monolayer...

Semiconducting materials such as CdSe, CdS, PbS and GaP are included in crystalline zeolite Y and mordenite and structurally flexible ethylenemethacrylic acid copolymer solid matrices. EXAFS anal sis reveals formation of while the polymer matrices allow agglomeration of larger semiconducting particles. Zeolite anchored structures are distinctively different to small particles with bulk crystal ...

Recently, freestanding lms have attracted much attention because they are highly useful in the fabrication of various nanodevices. Freestanding lms can be used on any substrate without deterioration of their own unique properties. Layerby-layer (LBL) deposition has been used widely in the synthesis of freestanding lms, especially of polymer lms with specic physical and mechanical propertie...

Perovskite materials have drawn a lot of interest recently due to their potential increase solar cell efficiency. This study uses the capacitance simulator (SCAPS-1D) develop and simulate perovskite made semiconductor materials. The design that has been suggested is Al:ZnO/ZnO/CdS/CsSnCl3 MoS2. analysis focuses on how different characteristics material affect device’s performance. data reveals ...
