In 2019,Journal of Physical Chemistry C included an article by Chen, Shanbao; Huang, Chengxi; Sun, Huasheng; Ding, Junfei; Jena, Puru; Kan, Erjun. Category: bromides-buliding-blocks. The article was titled 《Boosting the Curie temperature of two-dimensional semiconducting CrI3 monolayer through van der Waals heterostructures》. The information in the text is summarized as follows:
The integration of ferromagnetic and semiconducting properties in a single 2-dimensional (2D) material has been recognized as a fertile ground for fundamental science as well as for practical applications in information processing and storage. CrI3 monolayer has recently drawn much attention due to its 2D long-range ferromagnetic (FM) order. However, its Curie temperature (TC) is too low (∼45 K) for practical spintronic applications. Here, the authors show that the in-plane FM coupling of CrI3 can be remarkably enhanced by constructing a 2D heterostructure where CrI3 monolayer is supported on a nonmagnetic normal semiconductor/insulator substrate. Choosing MoTe2 monolayer as a substrate, the authors find that the CrI3/MoTe2 2D heterostructure is an intrinsic semiconducting ferromagnet with TC of ∼60 K. The TC can be further increased to ∼85 K by applying an out-of-plane pressure of ∼4.2 GPa. The doubling of the TC in this 2D heterostructure comes from the introduction of extra spin superexchange (Cr-Te-Cr) paths. These findings provide a promising pathway to improve ferromagnetism in 2D semiconductors, which can stimulate further theor. and exptl. interest. In the experimental materials used by the author, we found Indium(III) bromide(cas: 13465-09-3Category: bromides-buliding-blocks)
Indium(III) bromide(cas: 13465-09-3) is used as a catalyst to produce dithioacetals when unactivated alkynes react with thiols and fields such as optics and microelectronics that utilize semiconductor technology have wide uses for indium in high-performing solar cells.Category: bromides-buliding-blocks
