An intrinsically switchable, monolithic BAW filter using ferroelectric BST
(IEEE-Inst Electrical Electronics Engineers Inc, 2016)This letter presents an intrinsically switchable monolithic filter based on laterally acoustically coupled bulk acoustic wave resonators. The filter is based on a barium strontium titanate-on- silicon (BST-on-Si) composite ... -
Electrical characteristics of a schottky device based on maleic anhydride deposited on p-type silicon by spin coating technique
(Natl Inst Optoelectronics, 2014)Al/Maleic Anhydride (MA)/p-Si metal-polymer-semiconductor (MPS) structures were prepared on p-Si substrate by spin coating and these MPS structures had a good rectifying behavior. The capacitance-voltage (C-V) and ... -
Characteristic evaluation on spray-deposited WFTO thin films as a function of W doping ratio
(Nonferrous Metals Soc China, 2014)In this work, F and F + W simultaneously doped SnO2 highly transparent conducting thin films were deposited on glass substrates at (500 +/- A 5) A degrees C temperature by the spray pyrolysis method. Microstructural, ... -
Optimal c-type filter design to maximize transformer's loading capability under non-sinusoidal conditions
(Taylor & Francis Inc, 2014)The main purpose of this article is to employ the C-type passive filters for maximization of the loading capability of transformers under non-sinusoidal conditions. For this aim, an optimal passive filter design approach ... -
Structural characterizations and optical properties of inse and inse:ag semiconductors grown by bridgman/stockbarger technique
(Elsevier Science Bv, 2014)Undoped InSe and Ag doped InSe (InSe:Ag) single crystals have been grown by using the Bridgman/Stockbarger method. The freshly cleaved crystals have mirror-like surfaces even without using mechanical treatment. The structure ... -
Investigation of diode parameters using I-V and C-V characteristics of Al/maleic anhydride (MA)/p-Si structure
(Indian Acad Scıences, 2014)Al/maleic anhydride (MA)/p-Si metal polymer semiconductor (NIPS) structures were prepared on p-Si substrate by spin coating. Device parameters of Al/MA/p-Si structure have been determined by means of capacitance voltage ... -
