Abstract
Official abstract text for this publication.
A pyroelectric device having a substrate and a first electrode overlying at least a portion of the substrate. A plurality of spaced apart nanometer sized pyroelectric elements are electrically connected to and extending outwardly from the first electrode so that each element forms a single domain. A dielectric material is deposited in the space between the individual elements and a second electrode spaced apart from said first electrode is electrically connected to said pyroelectric elements.
First claim
Opening claim text (preview).
We claim: 1. A pyroelectric device comprising: a substrate, a first electrode overlying at least a portion of said substrate, a plurality of spaced apart nanometer sized pyroelectric elements electrically connected to and extending outwardly from said first electrode, and a second electrode spaced apart from said first electrode and electrically connected to said pyroelectric elements. 2. The pyroelectric device as defined in claim 1 and comprising a dielectric material disposed between said pyroelectric elements. 3. The pyroelectric device as defined in claim 1 and comprising an adhesion layer between said first electrode and said substrate. 4. The pyroelectric device as defined in claim 1 and comprising a heat absorbing layer overlying at least a portion of said second electrode. 5. The pyroelectric device as defined in claim 1 and comprising a plurality of recesses formed on a side of said substrate opposite from said first electrode. 6. A pyroelectric device comprising: a substrate, a first electrode overlying at least a portion of said substrate, a plurality of spaced apart nanometer sized pyroelectric elements electrically connected to and extending outwardly from said first electrode, a dielectric material disposed between said pyroelectric elements, a plurality of recesses formed on a side of said substrate opposite from said first electrode and a second electrode spaced apart from said first electrode and electrically connected to said pyroelectric elements. 7. The pyroelectric device as defined in claim 6 further comprising a heat absorbing layer overlying at least a portion of said second electrode. 8. The pyroelectric device as defined in claim 6 wherein pyroelectric elements comprise free space, a gas or a mixture of gasses, inert gas or a mixture of inert gasses, air or a combination thereof. 9. The pyroelectric device as defined in claim 6 wherein nanometer sized pyroelectric elements have a diameter of less than 15 nanometers. 10. The pyroelectric device as defined in claim 6 wherein nanometer sized pyroelectric elements have a diameter of less than 10 nanometers. 11. The pyroelectric device as defined in claim 6 wherein nanometer sized pyroelectric elements have a diameter of less than 8 nanometers. 12. The pyroelectric device as defined in claim 1 wherein pyroelectric elements comprise free space, a gas or a mixture of gasses, inert gas or a mixture of inert gasses, air or a combination thereof. 13. The pyroelectric device as defined in claim 1 wherein nanometer sized pyroelectric elements have a diameter of less than 15 nanometers. 14. The pyroelectric device as defined in claim 1 wherein nanometer sized pyroelectric elements have a diameter of less than 10 nanometers.
