Abstract
Organic Source‐Gated Phototransistors with > 104 Photo‐To‐Dark Current Ratio
Contact‐controlled transistors versatile thin‐film devices have promising potential in emerging sensors and user interfaces. The most mature of these, source‐gated transistors (SGTs), have excellent signal gain and uniformity characteristics. In article 2301931, Hagen Klauk, Radu A. Sporea, and co‐workers demonstrate organic SGTs fabricated using organic semiconductor DNTT, with superior geometrical and temporal stability. These structures show high sensitivity to blue light in a simple‐to‐implement, robust architecture, and the functionality can be generalised to numerous topical areas, including low‐cost light sensors for wellbeing, health, and environmental applications.
