Currently, semiconductor nanomaterials and devices are still in the research stage, but they are promising for applications in many fields, such as solar cells, nanoscale electronic devices, light-emitting nanodevices, laser technology, waveguide, chemicals and biosensors. Further development of nanotechnology will certainly lead to significant breakthroughs in the semiconductor industry. The book describes the most important II-VI semiconductors with applications in solar cells, optoelectronics and electronic devices. CdS, CdSe, ZnS and TiO2 nanoparticles were synthesized by the wet chemical...

The present book is aimed towards the development of NLO single crystals of p-Toluidine p-Toluenesulfonate, L-Proline Succinate, L-Arginine semicarbazide and L-lysine sulphate are exhibiting NLO property more than that of KDP, and these grown materials can be used as a better replacement for KDP to find applications in the field of opto-electronics. These crystals belong to the amino acid group, which exhibit the nonlinear optical (NLO) property remarkably. The characterization studies include single XRD analysis, UV analysis, mechanical and dielectric studies of the grown crystals. The...

The book consists of six chapters. PbS, CdTe, ZnSe, Zn-CdS and CdS thin films were grown by chemical bath deposition (CBD) technique. The crystal structure and crystallite size of the thin films were determined using X-ray diffraction (XRD). The optical properties were studied by the Ultraviolet-Visible (UV-Vis) absorption spectrum. The particle size and morphology were studied using Scanning electron microscope microscopy. The dielectric properties of thin films were studied in the frequency range of 50Hz-5MHz at different temperatures. Further, electronic properties like valence electron...

The book is to outline in qualitative terms, the way in which the dielectric constant varies with frequency and temperature, and to indicate the type of information regarding the structure of materials which can be obtained from the study of the dielectric constant. The various types of polarizations, which have been demonstrated to exist, are listed, together with an outline of their characteristics. The development of the dielectric theory in recent years has been along such specialized lines that there is a need for some correlation between the newer and the older theories of dielectric...
