Higher Property Control of Defects in 2D Materials 2DMaterials nanomachining spectroscopy NanoLetters
By Hussain AhmedSep 22 2022Reviewed by Megan Craig, M.Sc. Customizing the features and functionality of two-dimensional substances is inextricably linked to defect engineering. Traditional techniques, particularly in non-vacuum settings, do not provide the required control to incorporate and investigate defects in 2D substances.
Nanomachining provides novel techniques for constructing 2D materials for optoelectronic devices, catalyst supports, and quantum communication applications. Carefully chosen hBN defects exhibit quantum behavior at ambient temperature, offering a new framework for complex 2D quantum equipment. Additionally, standard diagnostic techniques like optical spectrophotometer, mass spectroscopy, and X-ray photoluminescence spectroscopy are used to evaluate the response of induced defects.
Novel Nanomachining Techniques for Defect Engineering Scanning probe microscopy and other novel nanomachining methods have recently been created for defect engineering of 2D nanomaterials. The mechanism of light-matter interaction near the AFM tip was studied, along with the effects of incident beam power, time of exposure, and environmental factors. Nano-infrared spectroscopy was used to characterize the modifications in chemical fingerprints affiliated with defect formation.
