ZnO/CdS Core-shells Optical Sensor fabrication using Chemical Method
ISBN: 9783659203633 / Angielski / Miękka / 2012 / 60 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book focuses on fabrication of ZnO/CdS optical sensor. Nanocrystalline ZnO/CdS core-shell optical sensors were fabricated by chemical bath deposition (CBD) method. Vertically aligned ZnO nanorods were firstly synthesized on silicon p-type (111) by CBD method with assist of microwave. The CdS were deposited on the ZnO nanorods to create core-shell structure by using CBD method with cadmium chloride (CdCl2) 0.15M as Cd2+ ion source at difference deposition time. ZnO nanorods were the core and CdS were the shell of this core-shell structure. The photoconductive testing was carried out to...

Design of Metal-Semiconductor- Metal Photodetector
ISBN: 9783659222351 / Angielski / Miękka / 2012 / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book explain the conditions in forming porous silicon and we compare the differences on porous formation using alternating current (AC) and direct current (DC) conditions.The purpose of porous is to change energy gap and surface area of silicon substrate. By making porous on silicon substrate, the photodetector device will become more efficient than the normal silicon substrate. The basic idea of metal-semiconductor-metal photodetector based porous silicon is to reduce the light reflection in order to enhance the light sensitivity and on the other hand to enhance the effects of the...

Effect of Microfibril Angle on the Properties of Acacia Mangium Wood
ISBN: 9783845439631 / Angielski / Miękka / 264 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The main purpose of this study is to provide the knowledge and data on the physical, mechanical and nanostructural properties of Acacia mangium wood from Sabah. A further objective was to examine the influence of microfibril angle (MFA) on strength, stiffness, tree age, the distance from pith to bark and the internal structure of the wood and to predict the perfect growth age which produces pure crystalline cellulose and more ordered. The results show that the fully grown which produce fully crystalline cellulose will denote as the optimum age (ao) was found to be 23.45 year for the pith...
