2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

A novel Q‐band asymmetric T/R switch in GaAs pHEMT using second‐order band‐stop filter for wideband RX‐mode isolation

Electronics Letters, 2023
To improve the RX‐mode isolation of asymmetric T/R switches, a new circuit topology is proposed. The proposed asymmetric T/R switch topology features a second‐order band‐stop filter in its TX path, which extends the bandwidth of isolation in the RX mode.
