Preparation of Metal-Thin Film-Metal Device Structure for Pyroelectric Heat Sensor Measurement

Öz

In this study, the pyroelectric properties of organic Langmuir-Blodgett (LB) thin film material produced at the nanometer scale were investigated. LB thin films obtained by transferring organic molecules floating on the water surface to the solid surface were produced in an unsymmetrical structure. Steric acid and eicosylamine molecules were selected to fabricate unsymmetrical LB film structure. This structure was used to investigate the pyroelectric and electrical (C-f and C-tan δ) measurements. The pyroelectric figure of merit (FOM) was determined using pyroelectric constant, the dielectric constant value and dielectric loss. The value of FOM for the stearic acid/eicosylamine LB film was determined as 0.530 Cm-2K-1 .

Anahtar Kelimeler

• Pyroelectric effect

Öz

Bu çalışmada, nanometre ölçeğinde üretilen organik Langmuir-Blodgett (LB) ince film malzemesinin piroelektrik özellikleri incelenmiştir. Su yüzeyinde yüzen organik moleküllerin katı yüzeye aktarılmasıyla elde edilen LB ince filmler simetrik olmayan bir yapıda üretilmiştir. Simetrik olmayan LB film yapısını imal etmek için sterik asit ve eikosilamin molekülleri seçildi. Bu yapı, piroelektrik ve elektriksel (C-f ve C-tan δ) ölçümlerini araştırmak için kullanıldı. Piroelektrik figüre of merit (FOM) değeri piroelektrik sabiti, dielektrik sabiti değeri ve dielektrik kaybı kullanılarak hesaplandı. Sterik asit/eikosilamin LB filmi için FOM değeri 0.530 Cm-2K-1 olarak elde edilmiştir. .
