The 1T-MoS2 monolayer is a slab of hexagonal Mo lattice occupies at the center by octahedral coordination between two layers of hexagonally packed S atoms [27]. The coordination of the Mo metal and its d-electrons play an important role in manipulating the electronic property of MoS2 nanosheets [10], [13].

What is 1T and 2H MoS2?

MoS2 generally exhibits two kinds of crystalline phases: hexagonal 2H phase and octahedral 1T phase. 1T-MoS2 exhibits much better chemical/physical properties than natural semiconductor 2H-MoS2. However, 1T-MoS2 is metastable and its synthesis is still a challenge.

What is 2H MoS2?

MoS2 (2H phase) is a semiconductor with an indirect band gap of 1.2 eV. … Molybdenum Disulfide is used for example as a photodetector and transistor. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers.
