  2. 1. Quantum Hall devices on epitaxial graphene: towards large-scale integration

    Author : Arseniy Lartsev; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum Hall effect; resistance metrology; epitaxial graphene; quantum Hall array; magnetotransport;

    Abstract : Quantum Hall devices have been used as the primary standard of electrical resistance for over two decades, and they are unlikely to be replaced in this role any time soon. The work presented in this thesis was being done towards the goal of establishing epitaxial graphene on silicon carbide as a new material of choice for these devices. READ MORE

  4. 2. Enabling technologies for scalable graphene electronics

    Author : Naveen Shetty; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; edge contact; Hall effect; graphene; 2d-tech; array; 1 f; metrology;

    Abstract : This thesis addresses the challenges in scaling up graphene-based technologies, with a focus on the epitaxial growth of graphene (epigraphene) over SiC substrates and the establishment of reliable low-contact resistance electrical contacts. The scalable graphene growth and contact fabrication have enabled the development of three epigraphene-based devices, including large-scale Quantum Hall Arrays, highly sensitive Hall effect magnetometers with minimal noise, and quantum-limited ultraviolet (UV) detectors.
