Solution‐Processed Tunable Spectral Response Photodetectors Enabled by Acidochromic Polymers

Advanced Electronic Materials, Volume 12, Issue 11, 8 June 2026.
Tunable spectral response photodetectors have been fabricated by using acidochromic polymers in photodiode and phototransistor geometries with organic/inorganic semiconductor heterojunctions. The spectral response of the photodetector has been tuned from the visible to the NIR region by using vapor‐phase trifluoroacetic acid (TFA) in a reversible way ...

Oligomer semiconductor/dielectric interface modification for organic thin film transistor hysteresis reduction

, 2014
In this work, we investigate the hydroxyl group effect on hysteresis of the low voltage organic thin film transistor (OTFT). A high k material, hafnium oxide, is utilized as gate dielectric to reduce OTFT operational voltage.
