老字号的法律保护研究

中国在法律方面没有清晰地定位老字号的相关内容,存在很多缺陷和不足,也无法协调各方面的法律,对其合法权益的维护也很难实现,实际中,很多老字号的权利都存在被侵犯的情况,世界范围内很多国家都详细规定了保护老字号的要求,因此,中国必须制定《字号法》,将《商标法》和字号登记制度进行优化和完善,从而充分保护老字号。

Large Photoluminescence Enhancement by an Out-of-Plane Magnetic Field in Exfoliated WS2 Flakes

We report an out-of-plane magnetic field induced large photoluminescence enhancement in WS2 flakes at 4K,in contrast to the photoluminescence enhancement provided by an in-plane field in general.Two mechanisms for the enhancement are proposed.One is a larger overlap of the electron and hole caused by the magnetic field induced confinement.The other is that the energy difference between varLambda and K valleys is reduced by magnetic field,and thus enhancing the corresponding indirect-transition trions.Meanwhile,the Landé g factor of the trion is measured to be-0.8,whose absolute value is much smaller than normal exciton,which is around-4.A model for the trion gfactor is presented,confirming that the smaller absolute value of the Landé g factor is a behavior of this A–Ktrion.By extending the valley space,we believe this work provides a further understanding of the valleytronics in monolayer transition metal dichalcogenides.
