Latest Patents

Uthamalingam holds a patent for a PLZT capacitor and method to increase the dielectric constant. This invention involves a ceramic capacitor that includes a first electrically-conductive layer, a second electrically-conductive layer arranged proximate to the first, and a dielectric layer interposed between them. The dielectric layer is formed of a lead-lanthanum-zirconium-titanate material (PLZT), characterized by a dielectric constant greater than 125 when measured at 25 degrees Celsius and zero volts bias, and an excitation frequency of ten-thousand Hertz (10 kHz). The method for increasing the dielectric constant includes depositing PLZT to form the dielectric layer and heating the ceramic capacitor to a temperature not greater than 300°C.
