DNA moiré superlattices. [PDF]

Nat Nanotechnol
Abstract Moiré superlattices have been extensively designed and implemented in atomic-scale van der Waals systems and submicrometre-scale photonic systems. However, bridging the structural gap between these scales has remained a substantial challenge. Here we demonstrate engineered DNA moiré superlattices with sublattice constants as small as

Spin-Filter Magnetic Tunnel Junctions Based on A-Type Antiferromagnetic CrSBr with Giant Tunnel Magnetoresistance

Magnetochemistry, 2022
CrSBr is a stable two-dimensional (2D) van der Waals (vdW) magnet with intralayer ferromagnetic and interlayer antiferromagnetic couplings. Here, we propose to use CrSBr as the barrier in spin-filter (sf) MTJ and establish the devices based on graphene ...
