Low-power beam makes laser-induced graphene
Scientists have made laser-induced graphene with a low-power laser mounted in a scanning electron microscope, an advance expected to lead to the wider commercial production of flexible electronics and sensors.
The process creates Laser-induced graphene (LIG) with features over 60 per cent smaller than the macro version of the material and almost 10 times smaller than typically achieved with an infrared laser.
The findings, developed in the labs of Rice University chemist James Tour and Tennessee/ORNL materials scientist Philip Rack, are detailed in ACS Applied Materials & Interfaces.

"A key for electronics applications is to make smaller structures so that one could have a higher density, or more devices per unit area," Tour said in a statement. "This method allows us to make structures that are 10 times denser than we formerly made."
