Tunable Charge Transport Properties Through Precise π‐Stacking Modulation in Isostructural Porous Molecular Conductors

open access: yesAngewandte Chemie, EarlyView.
An intrinsic structure–property relationship in through‐space conductive MOFs is investigated using a series of counterion‐free porous molecular conductors (PMC‐3) with carrier‐doped π‐stacked columns. The constant carrier density and halide‐dependent tunable π‐stacking geometry in PMC‐3 enable the discovery of a linear correlation between the lattice ...

Gate Enhancing Charge‐Spin Conversion in Organic Chiral Field Effect Transistors

open access: yesAdvanced Science, EarlyView.
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.

Exchange Length Tailored Magnetic Resonance for Broadband Absorption in FeCo‐Based Alloys

open access: yesAdvanced Science, EarlyView.
To break the high‐frequency magnetic loss bottleneck in soft magnetic alloys, a magnetic exchange length (Lex)‐guided strategy is proposed. Cu doping increases Lex and intergranular coupling, which effectively reduces magnetic anisotropy and pushes the exchange resonance to 12.0 GHz.
