This book was released on 2012 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zinc nitride thin films possess a small optical band gap with direct transition, low resistivity, high mobility and carrier concentration. Therefore, it may be suitable as an optoelectronic material for infrared sensors, smart windows and energy conversion devices. The objective of this work is to grow zinc nitride thin films using RF magnetron sputtering, understand its mechanical, optical, and electrical properties, and investigate its performance as light sensing devices. Synthesis and characterization of zinc nitride thin films has been investigated in this work. An RF magnetron sputtering deposition was employed to synthesize zinc nitride thin films using pure metal zinc target in either N2-Ar or N2-Ar-H2 mixtures. The microstructural, optical and electrical characterizations of the representative films were investigated with stylus profilometry, XRD, AFM, SEM, TEM, UV-VIS-NIR double beam spectrometry, and Hall effect measurement. The photoresponse of the zinc nitride photoconductors was also studied under the irradiation of white light and NIR light. The as-deposited zinc nitride thin films were relatively soft and densely packed with smooth surface. It possesses a narrow optical band gap in the NIR range with direct transition. The zinc nitride showed n-type conductivity with low resistivity and high carrier concentration. To study the RF discharge power effect, the zinc nitride thin films were synthesized at different discharge powers densities. With discharge power density increasing, the film deposition rate increased, and the zinc nitride films acquired better crystalline structure, smaller optical band gap and less oxygen contaminations. After thermal annealing at moderate temperatures in either air or O2, the annealed zinc nitride thin films were photoconductive under irradiation of both NIR light and white light. The largest photoresponse and fastest response times were measured at the room temperature for the zinc nitride thin films annealed at 300 degree in the air. Hydrogen inclusion can modify the electrical and optical properties of crystalline semiconductor films by introducing impurity donor states. The ZnNx:H films deposited in N2-Ar-H2 mixture acquired less oxygen contamination and higher relative nitrogen atom concentration than the ZnNx films deposited in N2-Ar mixture. The as-deposited ZnNx:H films showed a clear photonic behavior under white light irradiation, and the annealed ZnNx:H films exhibited a pronounced change in resistance under both white light and NIR light irradiation comparing to the annealed ZnNx films. This was the first time to report photoresponse of zinc nitride thin films fabricated by reactive sputtering method. The photoconductivity was gradually improved by optimization of deposition conditions, annealing conditions and film compositions.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes the different implantation mechanisms which can be used to achieve strong, reliable and stable p-type ZnO thin films. The results will prove useful in the field of optoelectronics in the UV region. This book will prove useful to research scholars and professionals working on doping and implantation of ZnO thin films and subsequently fabricating optoelectronic devices. The first chapter of the monograph emphasises the importance of ZnO in the field of optoelectronics for ultraviolet (UV) region and also discusses the material, electronic and optical properties of ZnO. The book then goes on to discuss the optimization of pulsed laser deposited (PLD) ZnO thin films in order to make successful p-type films. This can enable achievement of high optical output required for high-efficiency devices. The book also discusses a hydrogen implantation study on the optimized films to confirm whether the implantation leads to improvement in the optimized results.

This book was released on 2017-06-19 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The II-VI compound semiconductors are of great importance due to their application in various electro-optic devices. Thin films of ZnS find many more applications in the area of opto electronic device fabrication like UV light emitting diodes, blue light emitting diodes, emissive flat screens, electroluminescent devices and antireflection coating in solar cell technology. Several methods have been used to prepare ZnS thin films. We have deposited ZnS films using chemical bath deposition method using sodium hydroxide as a complexing agent. The structural and morphological characteristics of films have been investigated by X-ray diffraction (XRD) and scanning electron microscope. XRD shows deposited film was polycrystalline nature with cubic structure. The grain size is estimated to be in the range of 35-70 nm. The crystallinity of the ZnS film was analysed by HRTEM with the help of the electron diffraction pattern. The films show good optical properties with high transmittance in the visible region and the band gap value were found 3.3 eV - 2.1 eV. ZnS films can be used as buffer layers on CdTe solar cells.
