616951 news 1548667474 1548672415 <![CDATA[Techniques for manipulation of 2D materials and the creation of new devices ]]> The ability to manipulate 2-D materials at the wafer scale is an important step on the path to industrialisable production of 2-D optoeletronics and nanoelectronic devices. A breakthrough reported in Science has been made by an international partnership demonstrating a novel technique that allows for waferscale separation of 2-D materials from their growth substrate in a few minutes, permitting fast fabrication cylcles lasting less than an hour. A second report, in Nature Materials, explores the feasibility of remote epitaxy for growth of arbitrary materials on 2-D layers. In this partnerhip, UMI GT-CNRS  contributed its expertise in production of 2-D h-BN materials.

Collaborators include GT-CNRS UMI-2958 researchers, MIT, Sun Yat-Sen University, the University of Virginia, the University of Texas at Dallas, the U.S. Naval Research Laboratory, and Ohio State University and Yonsei University in South Korea.

The recent research results have been highlighted by CNRS (french language):

]]> 2019-01-28T00:00:00-05:00 2-D materials are promising for the creation of ultra-cheap flexible electronics using special purpose optoelectronic semiconductors such as Gallium Nitride.  A recent collaboration has led to major advances in the ability to transfer of 2-D materials for device fabrication and in the understanding of a technique called "remote epitaxy", which allows the growth of arbitrary materials on 2-D layers. These layers can then be easily transfered to other supports or transfered and integrated with other semiconductor materials.  This breakthrough technique has the potential to make devices based on 2-D materials commercially viable.
