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.
Publication in ACS nano
High performance graphene enabled water splitting device has been accepted for presentation at the upcoming 2014 IEEE IEDM conference in Dec, the premier device conference. Work is led by phd student Li Ji and a collaboration between several faculty including Prof. Ed Yu.
Prof. Akinwande Chairs two recent international workshops on 2D materials at MRS spring meeting and ARL.
The MRS 2014 spring meeting was focused on roll-to-roll graphene and co-organized and co-chaired by Prof. Rod Ruoff. International speakers from leading institutions and companies presented on the progress on this front. The event was sponsored by NSF, the Nascent ERC center, and Aixtron Inc.
The two-day event at ARL in August 2014 focused on the science and applications of 2D materials beyond graphene and featured researchers from the US, Europe, and South America. The event was sponsored by ARO, ARL and Nascent ERC center.
