Patterning of 2D materials by ultrasonic embossing

Abstract

2D Nanomaterials have been an intriguing class of atomically thick material where many researchers are genuinely trying to exploit and unleash the wide range of benefits they hold. This includes exceptional photonics, electronics, mechanical, optical, and thermal properties. Insights and comments on the potential these ultra-thin layered materials have is provided. With this comprehensive report, the author strives to determine suitable ultrasonic embossing parameters to create successful nanostructures in a controlled and optimal manner. The top-down mechanical exfoliation method, also known as the “Scotch-Tape” method is adopted to prepare graphene and tungsten diselenide flakes from its respective bulk materials and subsequently transferred onto silver substrate. The report is also further supported by experimental results and discussions followed by the conclusion on the effectiveness of ultrasonic embossing.
