In this preprint, layer thinning of exfoliated Tellurene nanosheets is investigated. Along with Te thinning, β-TeO2, an emerging 2D semiconductor oxide, is investigated and the optical emission is reported for the first time. The findings show evidence of large exciton binding energy in layered  β-TeO2 nanosheets.

The S20 is an engagement group part of G20 Summit. S20 focuses on proposing and recommending scientifically driven policies in different themes. This year's theme is Foresight: Science for Navigating Critical Transitions. Under this theme, there are 4 sub-themes which includes future of health, circular economy, digital revolution, and connecting the dots. Under the task force leader, Dr. Amer along with his colleagues are part of the coordination team for circular economy sub-theme. Read more about circular economy here.  

Dr. Amer will be serving as a guest editor for the special issue entitled " Emerging Technologies in Nanodevices and Energy Generation Applications" that will be published in Materials. 

In this Special Issue, emerging nanodevices using novel nanomaterials and their corresponding energy applications are discussed. This includes novel transistor structures, photonic nanodevices, emerging and optimized solar cells, innovative sensors at the nanoscale, emerging nanomaterial synthesis techniques, nanomaterial characterizations, nanodevice simulations and optimizations, and integrated nanodevices and systems. 

Deadline for submission is 15 June 2021. For more information, please visit this link.
