Improving zinc metal(Zn^(0))reversibility and minimizing the N/P ratio are critical to boosting the energy density of Zn^(0) ***,in reality,an excess Zn source is usually adopted to offset the irreversible zinc loss and guarantee sufficient zinc cycling,which sacrifices the energy density and leads to poor practicability of Zn^(0) *** address the above conundrum,here,we report a lean-Zn and hierarchical anode based on metal-organic framework(MOF)-derived carbon,where trace Zn^(0) is pre-reserved within the anode structure to make up for any irreversible zinc source *** allows us to construct low N/P ratio Zn^(0) full cells when coupling the lean-Zn anode with Zn-containing ***,high Zn^(0) reversibility(average Coulombic efficiency of 99.4% for 3000 cycles)and long full-cell lifetime(92% capacity retention after 900 cycles)were realized even under the harsh lean-Zn condition(N/P ratio:1.34).The excellent Zn reversibility is attributed to the hierarchy structure that homogenizes zinc ion flux and electric field distribution,as confirmed by theoretical simulations,which therefore stabilizes Zn^(0) *** lean-Zn anode design strategy will provide new insights into construction of high-energy Zn^(0) batteries for practical applications.

Two-dimensional (2D) semiconductors are likely to dominate next-generation electronics due to their advantages in compactness and low power consumption. However, challenges such as high contact resistance and inefficient doping hinder their applicability. Here, we investigate work-function-mediated charge transfer (modulation doping) as a pathway for achieving high-performance p-type 2D transistors. Focusing on type-III band alignment, we explore the doping capabilities of 27 candidate materials, including transition metal oxides, oxyhalides, and α−RuCl3, on channel materials such as transition metal dichalcogenides (TMDs) and group-III nitrides. Our extensive first-principles density functional theory (DFT) reveal p-type doping capabilities of high electron affinity materials, including α−RuCl3, MoO3, and V2O5. We predict significant reductions in contact resistance and enhanced channel mobility through efficient hole transfer without introducing detrimental defects. We analyze transistor geometries and identify promising material combinations beyond the current focus on WSe2 doping, suggesting new avenues for hBN, AlN, GaN, and MoS2. This comprehensive investigation provides a roadmap for developing high-performance p-type monolayer transistors toward the realization of 2D electronics.

Two-dimensional (2D) multiferroic materials have widespread application prospects in facilitating the integration and miniaturization of nanodevices. However, the magnetic, ferroelectric, and ferrovalley properties in one 2D material are rarely coupled. Here, we propose a mechanism for manipulating magnetism, ferroelectric, and valley polarization by interlayer sliding in a 2D bilayer material. Monolayer GdI2 is a ferromagnetic semiconductor with a valley polarization of up to 155.5 meV. More interestingly, the magnetism and valley polarization of bilayer GdI2 can be strongly coupled by sliding ferroelectricity, making these tunable and reversible. In addition, we uncover the microscopic mechanism of the magnetic phase transition by a spin Hamiltonian and electron hopping between layers. Our findings offer a new direction for investigating 2D multiferroic devices with implications for next-generation electronic, valleytronic, and spintronic devices.

Coupling two-dimensional(2D)materials with plasmonic nanoparticles(NPs)holds great potential for enhancing the photodetection performance in 2D ***,there are limitations in the detection spectral range and response speed of plasmonic 2D photodetectors based on transition metal dichalcogenides(TMDs)like MoS_(2).We have developed a fast and broadband MoS_(2)photodetector(denoted as MoS_(2)/WO_(3-x))by coupling semi-metal sub-stoichiometric WO_(3-x)NPs beneath,in contrast to traditional WO_(3-x)/MoS_(2)photodetectors with the opposite positions of MoS_(2)and WO_(3-x)*** photodetection performance is 10 times higher than the WO_(3-x)/MoS_(2)structure,and 100 times higher than the pristine MoS_(2)device,broadening the spectrum to near-infrared(NIR),achieving a maximum responsivity and detectivity that can reach 1.8×10^(4)A W-1,4.62×10^(13)Jones,respectively,under 940 nm *** response speed exceeds the state-of-the-art MoS_(2)photodetectors based on composite structures,unprecedentedly reaching the order of tens of *** understanding of WO_(3-x)NPs as well as light interaction with the MoS_(2)layer reveal that the exceptional photoelectric performance can be attributed to the synergistic effect of both the semimetal nature of the underneath WO_(3-x)NPs and the intact nature of the top MoS_(2)*** mechanism enhances optical absorption,expands the spectral range,and simultaneously speeds up optoelectronic effects.
