Gate Enhancing Charge‐Spin Conversion in Organic Chiral Field Effect Transistors
Room‐temperature organic chiral multiferroic field effect transistors are demonstrated, enabling bidirectional control between spin and charge. Specifically, spin polarization affects the ferroelectric polarization, and ferroelectric polarization, in turn, can modulate spin polarization and spin‐dependent transport.

Ion Crowding Effect in Unilaterally Downsized Perovskite Memristors
The downscaling of perovskite memristors incorporating monocrystalline nanoplates is accompanied by an ion crowding effect, which greatly enhances the local electric field in the vicinity of electrode. The highly controlled crowding of anions and vacancies results in anisotropic switching characteristics as well as unique morphology modification ...

Composites made of semiconducting carbon nanotubes and p‐type polymers, when adequately doped with molecular dopants, can exhibit highly delocalized charge carrier transport, showing high thermoelectric performances. The efficient charge delocalization is enabled by the reduced coulombic binding energy at high carrier concentration and the small ...

A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

The study demonstrates that dip coating at lower speeds significantly enhances the thermoelectric performance of P3HT by improving electrical conductivity. Contrary to expectations, this improvement is seemingly not due to polymer alignment but rather to better structural order achieved during slower solvent evaporation at lower dip coating speeds ...

A novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4), is introduced for efficient n‐doping in N2200, P(PzDPP‐CT2) and other organic semiconductors (OSCs). P2BF4‐doped OSC films exhibit exceptional thermal stability, maintaining electrical conductivity after heating at > 150 °C for 24 h. This stability allows organic thermoelectric devices based on
