The existence of a depolarization field in polarized ferroelectric materials was experimentally demonstrated in the 1970s 1,2. In the pioneering work of Wurfel et al. 2, a triglycine sulfate ...
Single layers of MoS 2 and MoSe 2 were optically pumped with circularly polarized light and an appreciable polarization was initialized as the pump energy was varied. The circular polarization of the ...
