Schematic of the generation of structured EVBs. The binary holographic phase masks can be engineered with the generalized spiral phase to shape the incident free electrons to generate structured EVBs with customizable intensity patterns. The phase mask is composed of nanoscale forked gratings fabricated on 100 nm-thick silicon nitride membranes. Credit: Opto-Electronic Advances (2024). DOI: […]
(a) Crystal structure of Bi/MnBi2Te4 vdW heterostructure. (b) Schematic diagram showing controllable magnetism and topological phase transition in the material. The magnetization orientation (Mi: i=x, y,z; red arrows) is tunable by applying strain (denoted by purple arrows) or magnetic field. QAH states with controllable Chern numbers are realized by changing the magnetization orientation or twisting […]
Faraday effect in a 2D semiconductor. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-47294-5 It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave when the light passes through the material. This property is utilized in […]
