Semiconductors In article number 1900621 , Chunli Zhang and co‐workers propose a multiferroic composite semiconductor (MCS) fiber consisting of two outer piezomagnetic layers (PM), two piezoelectric layers (PE) and a semiconducting core, and theoretically demonstrate that one can effectively manipulate the behaviors of carries such as transport properties with an applied magnetic field through magneto‐electro‐semiconductive (MES) couplings. The physical mechanism of this tuning method is that the induced polarization due to magnetoelectric effects makes carriers redistribute in structures. Such a magnetic field‐based control approach is remote and contactless. Hence, it has remarkable advantages compared with the stress‐ or strain‐based method and has potential and important applications in future piezoelectric semiconductor devices.
