【摘要】:二維原子晶體材料簡稱二維材料,因載流子遷移和熱量擴散都被限制在二維平面內,展現出了許多奇特的性質而受到了廣泛關注。二維材料的帶隙可調特性在場效應管、光電器件、熱電器件等領域應用廣泛。另外二維材料的自旋自由度和谷自由度的可控性使得二維材料在自旋電子學和谷電子學等領域也引發(fā)了深入的研究。不同的二維材料由于晶體結構的特殊性質導致了不同的電學特性或者光學特性的各向異性,包括拉曼光譜、光致發(fā)光光譜、二階諧波譜、光吸收譜、熱導率、電導率等性質的各向異性。這些各向異性特性在偏振光電器件、偏振熱電器件、仿生器件、偏振光探等領域擁有巨大的發(fā)展?jié)摿Α6S材料的各向異性還能夠用于實現器件性能的最優(yōu)化。文章介紹了各種二維材料的各向異性的最新研究進展。
[Abstract]:Two-dimensional atomic crystal materials, short for two-dimensional materials, due to carrier transport and heat diffusion are confined in the two-dimensional plane, showing a lot of strange properties, so it has been paid more and more attention. Field effect transistors, optoelectronic devices, thermoelectric devices and so on are widely used in two-dimensional materials. In addition, the spin degree of freedom and the controllability of valley degree of freedom of two-dimensional materials also lead to further research in the fields of spin electronics and valley electronics. Due to the special properties of the crystal structure, different two-dimensional materials have different anisotropy of electrical or optical properties, including Raman spectra, photoluminescence spectra, second-order harmonic spectra, optical absorption spectra, thermal conductivity. Anisotropy of conductivity and other properties. These anisotropic properties have great potential in the fields of polarization optoelectronic devices, polarized thermoelectric devices, bionic devices, polarized light detection and so on. Anisotropy of two-dimensional materials can also be used to optimize device performance. This paper introduces the latest research progress of anisotropy of various two-dimensional materials.
