Our invited review article on flexible 2D nanoelectronics (http://dx.doi.org/10.1038/ncomms6678 ) is now online at nature communications.
The review is timely and marks the 10 year anniversary of the pioneering works on graphene by Manchester and Georgia Tech groups.
The review article is a collaborative authorship with Jim Hone’s group at Columbia University.
The pressure dependent properties of monolayer MoS2 was recently published in nanoletters (Dec 2014) showing up to 12% direct gap modulation, the highest experimental bandgap modulation observed so far.
Congratulations to the UT, IISc, Rutgers, and Kaust teams that collaborated intimately on this research.
Previously, we reported the high-pressure/strain studies on bulk MoS2 resulting in the observation of semiconducting to metallic phase transition in nature communications. Congrats to Avinash and our collaborators.
Drs Sherry Chang, Nassibe Rahimi and Sk. Fahad Chowdhury graduated with PhD degrees in electrical and computer engineering this Summer 2015.
Sherry’s thesis topic was
“Device Physics and Device Mechanics for Flexible MoS2 Thin Film Transistors”.
Nassibe’s thesis topic was
“Graphene and MoS2 Devices for Wafer-Scale Integrated Silicon Nanotechnology”.
Fahad’s thesis topic was
“Design, Fabrication and Characterization of Field-Effect Transistors Based on Two-Dimensional Materials and Their Circuit Applications”.
Congratulations and we wish you all the best in your personal and professional development.
Graphene synthesis has been demonstrated on industry standard 300mm silicon wafers showing more 95% monolayer uniformity. Notably statistical studies reveal that wafer-scale polycrystalline graphene offers similar or superior electrical results than single-crystal cost-expensive synthesized graphene.
The work was done in collaboration with Aixtron the leading graphene equipment manufacturer.
