Paper Abstract

DNA-CTMA is an attractive material to explore for reconfigurable optical and electronic devices. Its dielectric constant at microwave frequencies can be tuned by applying a DC electric field. In this work, the origin of dielectric tunability and other ferroelectric-like behavior observed in DNA-CTMA films is investigated. Results suggest that the dominant polarization mechanism is ionic in nature and is caused by intentionally retaining excess ions in the DNA-CTMA precipitate during processing.
