Unveiling the giant polarisation ratio of chiral photoluminescence in MoS2 nanorolligami fabricated using a centre-to-edge rolling mechanism

{{output}}
We introduced mechanical strain to systematically roll monolayer (1-L) MoS2 into nanostructures with diameters ranging from 100 to 200 nm. The rolled MoS2 regions exhibit unique anisotropic optical behaviour compared to the flat regions (thickness ≤1 nm), as ... ...
