Infrared detectors can be used for a variety of applications such as: using in fiber-optic communications. Conventional technology for IR detectors is using p-i-n structure based on GaAs compound. This paper reports on the design and modeling of an IR detector using a p-i-n GaAs structure. Comsol software is used to simulate the model and the detector is discussed for terminal current, dopant p...
highly crystalline and pure lithium metasilicate (li2sio3) and lithium disilicate (li2si2o5) nanomaterials were synthesized by hydrothermal method and characterized by pxrd technique. the changes in the morphology and particle size of the synthesized nanomaterials with reaction time were investigated using sem technique. the uv-vis and photoluminescence spectra of the compounds were studied. th...

In this work facile sol-gel (pechni) method has been successfully established to synthesize Zn4B6O13 nanocrystals which have cubic crystals with lattice parameter: a =7.48 A. The structure and morphology of the obtained material were studied by X-ray diffraction (XRD), Infrared spectra (IR), scanning electron microscopy (SEM) and photoluminescence analysis. The experimental results show a band ...
Layered semimetallic van der Waals material $\mathrm{Ti}{\mathrm{Se}}_{2}$ has attracted a lot of attention because interplay charge density wave (CDW) state and superconductivity. Its sister compound ${\mathrm{TiS}}_{2}$, being isovalent to having the same crystal structure, shows semiconducting behavior. The natural question rises---what happens at transition point in $\mathrm{Ti}{\mathrm{Se}...
