Doped organic semiconductors are critical to emerging device applications, including thermoelectrics, bioelectronics, and neuromorphic computing devices. It is commonly assumed that low conductivities in these materials result primarily from charge trapping by the Coulomb potentials of dopant counterions. Here, we present a combined experimental theoretical study rebutting this belief. Using newly developed doping technique based on ion exchange, prepare highly doped films with several...
Abstract Conducting polymers are mixed ionic–electronic conductors that emerging candidates for neuromorphic computing, bioelectronics and thermoelectrics. However, fundamental aspects of their many-body correlated electron–ion transport physics remain poorly understood. Here we show in p-type organic electrochemical transistors it is possible to remove all the electrons from valence band even access deeper bands without degradation. By adding a second, field-effect gate electrode,...
Open-shell systems with extensive π-conjugation have fascinating properties due to their narrow bandgaps and spin interactions. In this work, we report neutral open-shell di- polyradical conjugated materials exhibiting intriguing optical magnetic properties. Our key design advance is the planarized geometry allowing for greater interaction between adjacent spins. This results in absorption emission near infrared at 803 1050 nanometers, respectively, demonstrate a unique electronic structure...
Magnetic resonance methods offer a unique chance for in-depth study of conductive organic material systems, not only accounts number charge carriers, but also allows manipulations spin dynamics particles. Here we present continuous-wave electrically detected magnetic on range conjugate polymers under transistor architecture, with tunability in both carrier concentration and drifting electric field. We demonstrate the general existence bipolaron between mobile trapped charges at condition,...
