YBa2Cu3ox Thin Film Bolometers for Room Temperature InfraredDetection

提出的工作的目的是开发一种低成本，简单的室温红外探测技术，使用YBa2Cu3O6薄膜在一个可以直接集成到硅信号处理电路的测热计结构中。要研究的材料是YBa2Cu3Ox，以其在低温下的超导性能而闻名（x=7）。YBa2Cu3O6（x=6）是300K时的低电导率半导体。YBa2Cu3Ox是一种铁电（Er=105-106），与HgCdTe和非晶硅等竞争材料相比，它具有本质上低的噪声。YBa2Cu3)6薄膜的氧含量可以精确调节，以获得所需的电导率和介电常数。这项提议的研究是有史以来第一次尝试利用YBa2Cu3O6的非超导相。我们相信，如果进行全面的研究，YBa2Cu3O6将超越所有现有的非冷却红外技术。* * *

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. ***
