High degree of circular polarization in WS(2) spiral nanostructures induced by broken symmetry
We present helicity resolved photoluminescence (PL) measurements of WS(2) spiral (SPI) nanostructures. We show that very high degree of circular polarization (DCP) (~94 ± 4%) is obtained from multilayer SPI samples at room temperature upon excitation with a circularly polarized laser at a wavelength...
