Low-Loss EELS Investigations on Atomically Thin MoxW(1-x)S2 Nanoflakes for Delving into Their Optoelectronic Properties

Investigations on Optoelectronic Properties of New low Gap Compounds Based on Pyrrole as Solar Cells Materials

In this paper theoretical study by using DFT method on three conjugated compound based on 2-styryl-5-phenylazo-pyrrole is reported. These dyes contain one carboxy, two carboxy and one sulfonic acid anchoring groups, the aim is to investigate their effects on the electronic structure. The theoretical knowledge of the HOMO and LUMO energy levels of the components is cannot be ignored in investiga...

Optoelectronic Devices Based on Atomically Thin Transition Metal Dichalcogenides

We review the application of atomically thin transition metal dichalcogenides in optoelectronic devices. First, a brief overview of the optical properties of two-dimensional layered semiconductors is given and the role of excitons and valley dichroism in these materials are discussed. The following sections review and compare different concepts of photodetecting and light emitting devices, nano...

INVESTIGATIONS ON OPTOELECTRONIC PROPERTIES OF DC REACTIVE MAGNETRON SPUTTERED CdTe THIN FILMS

In the present work two individual metallic targets of Cd and Te were used for the deposition of CdTe thin films on mica substrates from room temperature to 300 C by DC reactive magnetron sputtering method. XRD patterns of CdTe exhibit peaks at 2θ = 27.7, 36. 2 and 45.1, which corresponds to reflection on (2 0 0), (2 2 0) and (3 1 1) planes of CdTe cubic structure, respectively. The conductivit...

Investigations on the structural, electrical properties and conduction mechanism of CuO nanoflakes

Copper oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors, bio sensors, nano fluids and catalysis. In Recent past, more efforts have been received to design materials with different properties which is dependent on morphology.  In this work cupric oxide nano flakes were...
