Electron Transport in Quantum Dot Light‐Emitting Diodes

Advanced Electronic Materials, EarlyView.
This work reveals that electron transport in core/multi‐shell quantum dots is severely hindered by traps located at the core‐shell interface. These traps follow a Gaussian energy distribution with a density of approximately 1023 m−3 and a common energy level of 4.0 eV below the vacuum level.

Balancing Injection and Short‐Channel Effects in Organic Permeable Base Transistors via Thickness Scaling

Advanced Electronic Materials, EarlyView.
Organic permeable base transistors are shown to benefit from balanced control of the semiconductor layers above and below the permeable base. Simulations and experiments indicate that the top semiconductor layer affects charge injection and lateral transfer length, while the bottom layer modulates the collector‐induced short‐channel effects.

Decoupled Dielectric Optimization and YbOx Contact Engineering in All‐Spray‐Processed Oxide Thin‐Film Transistors

Advanced Electronic Materials, EarlyView.
Fully spray‐processed oxide thin‐film transistors are advanced by decoupling dielectric quality from contact energetics. Thermochemically densified MgO suppresses defect‐mediated leakage and improves electrostatic control, while an ultrathin YbOx interlayer induces a 1.67 eV work‐function shift that boosts mobility from ∼40 to ∼94 cm2 V−1 s−1.

Free Charge Generation in Organic Photoconversion Devices–the Impact of Electrostatic Potentials

Advanced Energy Materials, EarlyView.
Free charge generation in organic photovoltaic and photodetector devices typically requires an external driving force to separate bound excitons formed upon photoexcitation. This review details how electrostatic potentials, arising from molecular charge distributions in organic semiconductors, can impact interfacial energetic landscapes and promote ...
