The resistivity of the films drops compared with the as - grown films , but the temperature of maximum magnetoresistance reaches 287k , very close to the room temperature . therefore it is not only an important improvement to fabricate the cmr bolometer which can work near room temperature , but also a prospective research for other applications such as magnetic - sensors , spintronics devices and infrared detectors 同時,退火后薄膜的電阻率明顯下降,外加5t磁場時,最大磁電阻率溫度點上升到287k ,接近于室溫,這不僅為制作室溫超巨磁電阻測輻射熱儀打下了堅實的基礎,也為其它許多器件的應用提供了可能。

One of the most important directions in the study of colossal magnetoresistance materials is to fabricate the bolometer , which can work near the room temperature and shows an excellent performance , if the films can be prepared with the metal - insulator transition temperature ( tmi ) reaching to the room temperature 利用超巨磁電阻材料制作工作于室溫的高性能測輻射熱儀是國際上cmr應用研究的一個重要方向,而能否制備具有室溫轉變點的薄膜材料是其中的一個決定因素。

As one of the most important applications , cmr bolometer is fabricated using the lacamno3 films , which has a metal - insulator transition temperature at 300k . the archetypal bolometer is fabricated after the film is photolithographed , evaporated au electrodes and fixed 以制作室溫超巨磁電阻測輻射熱儀為目標,將t _ ( mt ) 300k , tcr 5的薄膜進行光刻、電極制作、封裝等處理制作測輻射熱儀原型器件。

An initial measurement is carried out and the result shows that the bolometer is still sensitive to the infrared signal even the intensity of the signal source is very weak , if the bolometer is in a proper temperature 初步的測量表明,在最佳工作溫度點附近,器件對信號具有靈敏的響應。這就為器件的進一步測量和制作奠定了基礎,也為熱探測、熱成像等工作的進行提供了可能。

V2o5 and vo2 thin films are a kind of outstanding chromogenics , and have a large potential for various applications , such as display devices , light storage devices , optical switch , bolometer , smart - windows and so on 主要應用于顯示器件、光學開關、光存儲、激光保護、輻射測熱裝置等,特別是在智能窗材料方面的應用已成為研究的熱點。
