A ferroelectric metal insulator (MIM) varactor structure incorporating a floating and coplanar waveguide (CPW) has been introduced here. The work of the proposed is based on field-dependent material properties (Ba, Sr) TiO 3 (BST) thin film. capacitance tunability 44% achieved for bias voltage 0...

Phonon Hall effect (PHE) has attracted a lot of attention in recent years with many theoretical and experimental explorations published. While experiments work on complicated materials, studies are still hovering around the phenomenon-based models. Moreover, previous microscopic theory was found unable to explain large thermal conductivity obtained by strontium titanate (STO). Therefore, an att...

Here, we report a previously unreported low-temperature curable barium strontium titanate (BaXSr1−XTiO3) or BST dielectric nanoparticle ink which shows high tunability for printed electronics/additive manufacturing applications. The newly formulated is optimized to print in aerosol jet printers and can be cured at 150°C, will allow the fabrication of tunable radio-frequency (RF) microwave (MW) ...

By means of thin film technology a reduction of size, cost, and power consumption of electronic circuits can be achieved. The required specifications are attained by proper design and combinations of innovative materials and manufacturing technologies. This thesis focuses on the development and fabrication of low-loss ceramic thin film devices for radio and microwave frequency applications. The...

Calcium (Ca2+), strontium (Sr2+), and barium (Ba2+) are expected to exert similar chemical and pharmacological effects. The effects of barium, strontium and calcium were studied on the contractions of rat phrenic nerve-diaphragm preparations, following electrical stimulation and their interactions with nifedipine (nif) and diltiazem (DZM) were also studied. Low doses of strontium chloride (SrCl...
