Graphene Quantum Dot with Divacancy and Topological Defects: A Novel Material for Promoting Prompt and Delayed Fluorescence of Tunable Wavelengths
Tushima Basak, Tista Basak, Alok Shukla
This work demonstrates the unique approach of introducing divacancy imperfections in topological Stone-Wales type defected graphene quantum dots for harvesting both singlet and tri…
Graphene quantum dots with Stone-Wales defect as a topologically tunable platform for visible-light harvesting
Tista Basak, Tushima Basak, Alok Shukla
In this work, we report for the first time the crucial role of topological anomalies like Stone-Wales (SW) type bond rotations in tuning the optical properties of graphene quantum…
Electron correlation effects and two-photon absorption in diamond shaped graphene quantum dots
Tista Basak, Tushima Basak, Alok Shukla
In quasi-1D -conjugated polymers such as \emph{trans}-polyacetylene and polyenes, electron correlation effects determine the "reversed" excited state ordering in which the lowes…
Optical signatures of electric field driven magnetic phase transitions in graphene quantum dots
Tista Basak, Alok Shukla
Experimental challenges in identifying various types of magnetic ordering in graphene quantum dots (QDs) pose a major hurdle in the application of these nanostructures for spintron…
Theory of Linear Optical Absorption in Diamond Shaped Graphene Quantum Dots
Tista Basak, Himanshu Chakraborty, Alok Shukla
In this paper, optical and electronic properties of diamond shaped graphene quantum dots (DQDs) have been studied by employing large-scale electron-correlated calculations. The com…
