产品概述
2H MoTe2 (α相MoTe2)是一种半导体和抗磁性体系,间接带隙为~1.2 eV。单晶2H-MoTe2具有直接带隙,带隙与层数成反比。它是一种直接带隙材料,仅适用于单层或双层。这些层通过范德华相互作用堆叠在一起,可以剥离成薄的二维层。MoTe2属于第六族过渡金属二硫族化合物(TMDC)。在HQ石墨烯中制备的α-MoTe2晶体具有典型的横向尺寸为~0.6-0.8 cm,呈六边形,具有金属外观。2H MoTe2是一种n型半导体,在室温下典型载流子密度为~1017cm-3。
2H MoTe2 (alpha phase MoTe2) is a semiconductor and a diamagnetic system with an indirect band gap of ~1.2 eV. Monolay 2H-MoTe2 have a direct band gap which is inversely proportional to the number of layers. It is a direct band gap material only for single layer or bilayer. Note that Molybdenum Ditelluride also exist in the 1T' MoTe2 phase which is a semi-metal (for more information on 1T' MoTe2 click here ). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. MoTe2 belongs to the group-VI transition metal dichalcogenides (TMDC).
The α-MoTe2 crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm, are hexagonal shaped and have a metallic appearance. The 2H MoTe2 is a n-type semiconductor, having a typical charge carrier density of ~1017cm-3 at room temperature.
1T'-MoTe2是一种顺磁性的Weyl半金属。β相MoTe2中的层通过范德华相互作用堆叠在一起,可以剥离成薄的二维层。β-MoTe2属于第六族过渡金属二硫族化合物(TMDC)。在HQ石墨烯中制备的1T′相MoTe2晶体具有典型的横向尺寸为~0.6-0.8 cm,矩形和金属外观。
1T'-MoTe2 is a Weyl semimetal and is paramagnetic. The layers in the beta phase MoTe2 are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. β-MoTe2 belongs to the group-VI transition metal dichalcogenides (TMDC). Note that MoTe2 also exist in the 2H-MoTe2 phase which is a semiconductor (for more information on 2H MoTe2 click here ).
The 1T' phase MoTe2 crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm, rectangular shaped and have a metallic appearance.
