Organic Semiconductors

For applications such as light-emitting diodes or solar cells, organic materials are nowadays in the focus of research. These organic molecules could be a promising alternative to currently used semiconductors such as silicon or germanium and are used in OLED displays. A major problem is that in man more

Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, healthcare, and optical communications. Long considered a holy grail i more

In mobiles, fridges, planes – transistors are everywhere. But they often operate only within a restricted current range. LMU physicists have now developed an organic transistor that functions perfectly under both low and high currents. Transistors are semiconductor devices that control voltage and c more

Recent theoretical studies show that charge transport in high-mobility organic semiconductors is limited by low-frequency vibrations because of strong non-local electron-phonon interaction. Here we investigate two high-electron-mobility organic semiconductors with similar molecular structures but co more

Here, we design and synthesize three new diketopyrrolopyrrole (DPP) derivatives with naphthalene, possessing large-scaled π-delocalized electronic structure, as the flanking groups and both linear (n-decyl and n-dodecyl) and branched (2-hexyldecyl) alkyl chains as substitutions as active layer for h more

Correction for ‘Diketopyrrolopyrrole based organic semiconductors with different numbers of thiophene units: symmetry tuning effect on electronic devices’ by Qian Liu et al., New J. Chem., 2018, DOI: 10.1039/c7nj03505e. more

Organic light-emitting device (OLED) is a solid-state light-emitting device based on organic semiconductors. Recent rapid advances in material chemistry have enabled white OLEDs to be used for general lighting and large-area flat panel displays. Efficacy of white OLED panel has reached 110 lm/W which exceeds that of fluorescent lamp. more
