Confocal Microscope Studies of MoS2 Layer Thickness

چکیده

We have been studying micro-luminescence of various exfoliated MoS2 akes using a confocal microscope. A crucial issue is to determine thickness of the investigated layer. The common way using atomic force microscopy, electron microscopy or the Raman spectroscopy requires moving the sample out from the confocal microscope experimental setup and looking for a particular exfoliated ake hidden among thousands of others. In order to preliminarily determine thickness of investigated layers we have performed a study on optical re ectivity and compared the results with the Raman spectroscopy investigations. In this way we were able to calibrate our experimental setup. Optical measurements are much faster than the Raman spectroscopy and can give a good estimation of MoS2 thickness.

We performed a nanoscale confocal absorption spectral imaging to obtain the full absorption spectra (over the range 1.5–3.2 eV) within regions having different numbers of layers and studied the variation of optical transition depending on the atomic thickness of the MoS2 film. Three distinct absorption bands corresponding to A and B excitons and a high-energy background (BG) peak at 2.84 eV dis...

Origin of Structural Transformation in Mono- and Bi-Layered Molybdenum Disulfide

Mono- and multi-layered molybdenum disulfide (MoS2) is considered to be one of the next generation anode materials for rechargeable ion batteries. Structural transformation from trigonal prismatic (2H) to octahedral (1T) upon lithium or sodium intercalation has been in-situ observed experimentally using transmission electron microscope during studies of their electrochemical dynamics processes....

Thickness dependence of surface energy and contact angle of water droplets on ultrathin MoS2 films.

We have performed a systematic density functional study of surface energy of MoS2 films as a function of thickness from one to twelve layers with the consideration of van der Waals (vdW) interactions using the vdW-DF and DFT-D2 methods. Both vdW schemes show that the surface energy will increase with the increase of the number of atomic layers and converge to a constant value at about six layer...

Fabrication of single-layer MS2 (M=Mo, W) nanosheets using Li battery setup

Lithium intercalation is a convenient method to prepare few-layer and single-layer MS2 (M=Mo, W) nanosheets. This method is, however, very time-consuming (few days) and it is difficult to control the reaction parameters. To overcome these drawbacks, we have proposed a method to use an Li battery set-up to significantly reduce the reaction time (few hours) and electrochemically intercalate lithi...
