Valley-related multiple topological phase transitions have attracted significant attention because they provide opportunities for fundamental research and practical applications. Unfortunately, however, there is no real material as of yet that can realize valley-related transitions. Here, through first-principles calculations model analysis, we investigate the structural, magnetic, electronic, properties...
Two-dimensional (2D) multiferroic materials have widespread application prospects in facilitating the integration and miniaturization of nanodevices. However, magnetic, ferroelectric, ferrovalley properties one 2D material are rarely coupled. Here, we propose a mechanism for manipulating magnetism, valley polarization by interlayer sliding bilayer material. Monolayer GdI2 is ferromagnetic semiconductor with up to 155.5 meV. More interestingly, magnetism can be strongly coupled...
Manipulation of the valley degree freedom provides a paradigm in quantum information technology. Here, through first-principles calculations and model analysis, we demonstrate that monolayer ${\mathrm{Cr}}_{2}\mathrm{COOH}$ MXene is promising candidate material for valleytronics applications. We reveal ferromagnetic semiconductor harbors features. Due to simultaneous breaking inversion symmetry time-reversal symmetry, valleys are polarized spontaneously. Moreover, polarization sizable both...
Developing robust, low-cost, and scalable catalysts for photoelectrochemical (PEC) water splitting devices is crucial the sustainable hydrogen evolution reaction (HER). MoS2 has emerged as a potent alternative to Pt-based HER. However, active sites of 2H-MoS2 are reported locate at edges, leaving large number inert basal planes useless. Herein, facile strategy activate plane via an in situ PEC protocol. Both experimental studies theoretical calculations reveal emergence O–Mo–S on planes,...
Efficient and selective CO2 electroreduction into value-added chemicals fuels emerged as a significant approach for conversion; however, it relies on catalysts with controllable product selectivity reaction paths. In this work, by means of first-principles calculations, we identify five (TM@MoSi2N4, TM = Sc, Ti, Fe, Co, Ni) comprising transition-metal atoms anchored MoSi2N4 monolayer, whose catalytic performance can be controlled adjusting the d-band center occupation supported metal atoms....
Off-plane polarization in two dimensional materials is significant during the designation of functional nano-devices. As a prototype, metal chalcogen-diphosphate CuInP2S6 monolayer selected, and structure transition from initial antiferroelectric (AFE) state to off-plane ferroelectric (FE) realized under combined action normal strain electric field. With introduce compressed strain, critical driven field for remarkably lowered, which favorable actual device operation avoids possible...
