9420961 Celik-Bulter The purpose of the proposed work is to develop a low-cost, simple room temperature infrared detection technology using YBa2Cu3O6 thin films in a bolometer structure that can be directly integrated to the silicon signal processing circuitry. The material to be investigated is YBa2Cu3Ox, well known for its superconductive properties at cryogenic temperatures (x=7). YBa2Cu3O6(x=6) is a low conductivity semiconductor at 300K. YBa2Cu3Ox is a ferroelectric (Er=105-106) and has intrinsically low noise when compared to competing materials like HgCdTe and amorphous silicon. The oxygen content of the YBa2Cu3)6 thin film can be precisely adjusted to obtain the desired conductivity and dielectric constant. The proposed investigation is the first ever attempt, to exploit the nonsuperconducting phase of YBa2Cu3O6. We believe YBa2Cu3O6 is going to surpass all existing uncooled IR technologies if a full investigation is done. ***

9420961 Celik-Bulter拟议工作的目的是开发一种低成本、简单的室温红外检测技术，在测辐射热计结构中使用YBa2Cu3 O6薄膜，可以直接集成到硅信号处理电路中。 要研究的材料是YBa_2Cu_3Ox，众所周知的是其在低温（x = 7）下的超导特性。 YBa_2Cu_3O_6（x = 6）在300K时是一种低电导率半导体。 YBa2Cu3Ox是铁电体（Er = 105 - 106），与HgCdTe和非晶硅等竞争材料相比，具有固有的低噪声。 可以精确地调节YBa2Cu3）6薄膜的氧含量以获得期望的导电率和介电常数。 这项研究是首次尝试利用YBa2Cu3O6的非超导相。 我们相信，如果进行全面的研究，YBa_2Cu_3O_6将超过所有现有的非制冷红外技术。 ***
