IP3 - Patterned Absorption Layers for Pyroelectric Detectors with Higher Sensitivity

Yvonne Querner, Volkmar Norkus & Gerald Gerlach
A basic requirement for achieving a high sensitivity of pyroelectric detectors is the effective conversion of incident infrared radiation into heat. In many applications absorption layers of different metals like silver, gold, nickel chrome, or platinum are used to increase the sensitivity of the pyroelectric sensor. Also, polymer coatings with special filler materials like carbon black are widely used for increasing the absorption properties in the infrared range. These methods have several disadvantages e.g. some...
