PMMA and Cytop are two polymers. Both of these materials were reported as gate dielectric for transistor. I need to know the bandgap of these two polymer.
Please, see these articles:
1. Influence of Doping Concentration on Dielectric, Optical, and Morphological Properties of PMMA Thin Films
The energy band gaps are in the range of 3.6 eV to 3.9 eV when the PMMA concentration increased.
2. Two-Dimensional Carrier Distribution in Top-Gate Polymer Field-Effect Transistors:Correlation between Width of Density of Localized States and Urbach Energy
3. A new thieno-isoindigo derivative-based D–A polymer with very low bandgap for high-performance ambipolar organic thin-film transistors
Thank you
You can use the Tauc plot method from absorption spectra to analyze the band gap.
