  1. 1. Organic functionalization of graphene for applications in energy storage devices and optoelectronics

    Författare :Cheng Peng; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene; aqueous energy storage; optoelectronics; organic functionalization; 2D materials;

    Sammanfattning : The emergence of one-atom layer thick materials, exemplified by graphene following its first exfoliation by Geim and Novoselov, has sparked significant research interest. Owing to their unique electronic structure, 2D materials are regarded as promising candidates for diverse applications, including field-effect transistors (FETs), solar energy harvesting, biological systems, water purification, and energy storage devices.
