Synchrotron-based research has shown that the ability to generate and hold a switchable electric field (ferroelectric behavior) is possible in materials as thin as 1.2 nanometers (one-billionth of a meter, several hundred thousand times smaller than the period at the end of this sentence).
Ferroelectric thin films have a broad range of applications for both military and industrial equipment including specialized light and infra-red sensors, memory systems involving holographic optical storage of unprecedented capacity, tuneable microwave components (useful for phase-array radar), and microelectromechanical systems.
The technological potential of these materials depends on maintaining stable ferroelectric properties as electronic devices continue to be miniaturized. Studying such devices requires
synchrotron-based techniques.
