Growth and Characterization of Lead-free Piezoelectric Single Crystals
Lead-free piezoelectric materials attract more and more attention owing to the environmental toxicity of lead-containing materials. In this work, we review our first attempts of single crystal grown by the top-seeded solution growth method of BaTiO₃ substituted with zirconium and calcium (BCTZ) and (K0.5Na0.5)NbO₃ substituted with lithium, tantalum, and antimony (KNLSTN). The growth methodology...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
An equivalent dipole analysis of PZT ceramics and lead-free piezoelectric single crystals
The recently proposed Equivalent Dipole Model for describing the electromechanical properties of ionic solids in terms of 3 ions and 2 bonds has been applied to PZT ceramics and lead-free single crystal piezoelectric materials, providing analysis in terms of an effective ionic charge and the asymmetry of the interatomic force constants. For PZT it is shown that, as a function of composition acr...
متن کاملInvestigations on Gel Grown Lead Iodide and Thin Films of Gel Grown Lead Iodide Single Crystals
Observations on Surface Microtopography of gel grown PbI crystals and thin films of gel 2 grown PbI crystals are reported. Initiation of 2 growth layers, interlacing pattern, dendritic growth, symmetry and asymmetry hexagonal arms and natural triangular etch pits were seen. The surface topography, of gel grown PbI crystals and 2 of thin films of gel grown PbI have been related to 2 the growth ...
متن کاملOrigin of giant piezoelectric effect in lead-free K1−xNaxTa1−yNbyO3 single crystals
A series of high-quality, large-sized (maximum size of 16 × 16 × 32 mm(3)) K1-xNaxTa1-yNbyO3 (x = 0.61, 0.64, and 0.70 and corresponding y = 0.58, 0.60, and 0.63) single crystals were grown using the top-seed solution growth method. The segregation of the crystals, which allowed for precise control of the individual components of the crystals during growth, was investigated. The obtained crysta...
