A Highly Tunable Barium Strontium Titanate Thin Film MIM Varactor With Floating Metal

نویسندگان

چکیده

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 0–10 V over frequency range 1–3 GHz. yields compact area, high density, reduced mask process (two masks).

Noise characteristics of an oscillator with a barium strontium titanate (BST) varactor

The phase noise of an oscillator with a thin-film barium strontium titanate (BST) capacitive tuning element, or varactor, is characterised and benchmarked against the same oscillator with a silicon semiconductor junction varactor. Phase noise tracks closely with varactor Q within a specific voltage range as expected. Compared to the semiconductor varactor-based oscillator, the BST-based oscilla...

An Investigation of PLD-Deposited Barium Strontium Titanate (BaxSr1-xTiO3) Thin Film Optical Properties

Reflectance and transmittance parameters of pulsed laser deposited barium strontium titanate (BST) were investigated using spectrophotometric methods. Three stoichiometries consisting of BaxSr1−xTiO3 (x = 0.30, 0.40, 0.50) were deposited on glass substrates using oxygen partial pressures of 1.3 Pa ± 0.13 Pa at 500 ̊C. Subsequently, the measured optical parameters were employed to determine the r...

Electrooptic modulation in thin film barium titanate plasmonic interferometers.

We demonstrate control of the surface plasmon polariton wavevector in an active metal-dielectric plasmonic interferometer by utilizing electrooptic barium titanate as the dielectric layer. Arrays of subwavelength interferometers were fabricated from pairs of parallel slits milled in silver on barium titanate thin films. Plasmon-mediated transmission of incident light through the subwavelength s...
