WebApr 7, 2024 · Here, this work reports for the first time the large-area structure-selective synthesis of monolayer MoSe 2 and spiral MoSe 2 using a flux-controlled chemical vapor deposition method. Under a low MoSe 2 flux condition, monolayer MoSe 2 is synthesized, whereas thick spiral MoSe 2 is synthesized under a high flux condition. WebA simple method for designing and calculating grating optical filters with angular-selective light transmission is presented. The selectivity is provided by the relative positions of two surface gratings formed by directionally transmissive strips, alternating with absorptive, reflective, or scattering strips.
