Substrate Induced Optical Anisotropy in Monolayer MoS$_2$

Autor: Shen, Wanfu, Wei, Yaxu, Hu, Chunguang, Lopez-Posadas, C. B., Hohage, Michael, Sun, Lidong

In-plane optical anisotropy has been detected from monolayer MoS$_2$ grown on a-plane (11-20) sapphire substrate in the ultraviolet-visible wavelength range. Based on the measured optical anisotropy, the energy differences between the optical transit

Report

Direct observation of the CVD growth of monolayer MoS$_2$ using $in-situ$ optical spectroscopy

Autor: López-Posadas, C. B., Wei, Yaxu, Shen, Wanfu, Kahr, Daniel, Hohage, Michael, Sun, Lidong

Real-time monitoring is essential for understanding and eventually precise controlling of the growth of two dimensional transition-metal dichalcogenides (2D TMDCs). However, it is very challenging to carry out such kind of studies on chemical vapor d

The bottom-up fabrication graphene nanoribbons (GNRs) has opened new opportunities to specifically control their electronic and optical properties by precisely controlling their atomic structure. Here, we address excitations in GNRs with periodic str
