• Capacitors• Displays• Sensors• High-Performance Computing• Photovoltaics• Batteries and Fuel Cells
Researchers at the University of Nebraska—Lincoln have developed a method to electrochemically deposit organic dielectric materials on graphene.Quick Facts: • The thickness of the dielectric material can be controlled by changing the deposition time.• The electronic properties of graphene make it a highly desirable material for device applications and this method is one of only a few that exist to incorporate graphene into devices.• The fabrication method utilizes equipment that is common in the fields of semiconductor processing and electrochemistry.• The dielectric coatings can act as a seed layer so that high-κ dielectric materials can be combined with graphene in devices. • The deposition method provides pin-hole free dielectric layers that are necessary for use in devices.
