Pyroelectric Doping Reversal of MoS₂ p‐n Junctions on Ferroelectric Domain Walls Probed by Photoluminescence

Advanced Optical Materials, EarlyView.
The potential of pyroelectricity for controlling electron doping in monolayer MoS2 on periodically poled LiNbO3 substrates is demonstrated. Pyroelectric charges are shown to convert p‐n into n‐p homojunctions formed in MoS2 on domain walls. The variation in the MoS2 electron density from 300 to 10 K is consistent with the change in the spontaneous ...

Quantum Depletion of Superconductivity in 3D Diamond Nanowires

Advanced Quantum Technologies, EarlyView.
Heavily boron‐doped polycrystalline diamond nanowires demonstrate an exotic resistive state that alters the trend of the superconducting transition. This reentrant resistive state manifests itself as a peak in the current dependence of voltage and a negative magnetoresistance peak. This suggests that cross‐sectional grain boundaries can promote quantum‐
