The "magnetoelectric effect" arises from the coupling between magnetic and electric properties in materials. Z2 invariant of topological insulators (TIs) leads to a quantized version this phenomenon, known as magnetoelectric (TME) effect. This effect can be realized new phase called an "axion insulator" whose surface states are all gapped but interior still obeys time reversal symmetry. We demonstrate such using electrical transport measurements quantum anomalous Hall (QAH) sandwich...
Abstract Due to excellent electrical and optoelectronic properties, 2D transition metal dichalcogenides their van der Waals (vdW) heterostructures have attracted great attention for broadband optoelectronics. Here, an unreported vdW PdSe 2 /WS heterostructure is developed robust high‐performance photodetection from visible infrared optical communication band. These devices are simply formed by direct selenization of Pd films pre‐deposited on the chemical vapor deposited monolayer WS ,...
In this paper, we propose a quantum interference mediated control of switching between magnon-atom entanglement and magnon blockade. A three-level $\mathrm{\ensuremath{\Lambda}}$ configuration atomic ensemble yttrium iron garnet sphere are simultaneously coupled to microwave cavity mode through magnetic dipole interaction. By applying two strong fields drive the atoms, resonant coupling dressed-state transition mode, without direct interaction, is established by adiabatically eliminating...
Perovskite solar cells attract widespread attention due to their impressive power conversion efficiencies, high absorption coefficients, tunable bandgap, and straightforward manufacturing protocols. However, in the process of further development optimization toward mass production, long‐term stability stands as one most urgent challenges that need be overcome. Given excellent thermal structural designability, ionic liquids (ILs) are relatively green room‐temperature molten salts have been...
The rapid development of perovskite solar cells (PSCs) over the past decade makes it most promising next generation photovoltaic technology. Splendid progress in efficiency and stability has been demonstrated laboratory level, while endeavours are extremely required to enable successful transfer printable PSC technology industry scale toward commercialization. In this work, recent progresses on upscaling PSCs systematically reviewed. Starting with traditional structure, we have analyzed...
Chiral perovskites have attracted considerable attention owing to their potential applications in spintronic- and polarization-based optoelectronic devices. However, the structural chirality/asymmetry transfer mechanism between chiral organic ammoniums achiral inorganic frameworks is still equivocal, especially under extreme conditions, as systematic differences been rarely explored. Herein, we successfully synthesized a pair of new enantiomeric perovskite (S/R-3PYEA)PbI4 (3PYEA2+ =...
Time-periodic light field can dress the electronic states and lead to light-induced emergent properties in quantum materials. While below-gap pumping is regarded favorable for Floquet engineering, so far direct experimental evidence of momentum-resolved band renormalization still remains missing. Here, we report black phosphorus by at photon energy 160 meV, which below gap, distinction between near-resonance revealed. Our Letter demonstrates engineering upon pumping, provides insights...
We propose a scheme to generate nonreciprocal entanglement between an yttrium iron garnet (YIG) sphere and two nitrogen-vacancy-center ensembles by magnon Kerr effects in transmission-line resonator. By driving the YIG appropriately, strong nonlinearities emerge then induce parametric amplification frequency shift, resulting appearance of optimal entanglements. Depending on direction bias magnetic field, macroscopic is realized this all-solid-state quantum system, which may find potential...
Abstract The inverted perovskite solar cells based on hole‐selective self‐assembled molecules (SAMs) have been setting new efficiency benchmarks. However, the agglomeration of SAM and lack defect passivation ability are two critical issues that need to be addressed. It is demonstrated by blending co‐adsorbent 4‐phosphoricbutyl ammonium iodide (4PBAI) with 4‐(7H‐dibenzo[c,g]carbazole‐7‐yl) phosphonic acid (4PADCB), enhanced homogeneity, conductivity, better energy levels can realized for...

The power conversion efficiency HDPs‐based needs to be further improved before commercialization the market. It requires a thoughtful understanding correlation between specific structure property. Here, structural optical properties an important HDP‐based (NH 4 ) 2 SeBr 6 investigated under high...
We propose a scheme to generate remote asymmetric Einstein-Podolsky-Rosen (EPR) steering of two magnon modes in hybrid ferromagnet-superconductor system. In our scheme, the indirect coherent coupling between distant magnons and $\mathrm{\ensuremath{\Delta}}$-type superconducting atom is established via exchange virtual photons dispersive cavities. As consequence, artificial acting as reservoir can produce asymmetrical magnon-magnon single dissipation channel. Interestingly, we find that...
