Spectroelectrochemical Determination of Förster Radii for Triplet‐Polaron Quenching in Phosphorescent Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Phosphorescent OLEDs suffer from efficiency roll‐off due to triplet‐polaron quenching (TPQ). This study demonstrates for a large set of host‐guest combinations a spectroelectrochemical method to measure the absorption of charged molecules, enabling determining TPQ Förster radii (2.5–4 nm) from the spectral overlap.

A Novel Approach to Implementing Artificial Thalamic Neurons with Ferroelectric Transistors

Advanced Functional Materials, EarlyView.
Artificial neurons created using CMOS technology often require a large number of transistors and capacitors. This study introduces an artificial thalamic neuron that employs only five CMOS compatible ferroelectric transistors. The manufactured thalamic neuron demonstrates leaky integrate‐and‐fire‐or‐burst (LIFB) functionalities, featuring self ...
