Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator (2012)
Journal Article
Lulla, K., Cousins, R., Venkatesan, A., Patton, M., Armour, A., Mellor, C. J., & Owers-Bradley, J. (2012). Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator. New Journal of Physics, 14, doi:10.1088/1367-2630/14/11/113040

We present results from a study of the nonlinear inter-modal coupling between different flexural vibrational modes of a single high-stress, doubly-clamped silicon nitride nanomechanical beam. Using the magnetomotive technique and working at 100 mK we... Read More about Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator.

Scanning capacitance imaging of compressible and incompressible quantum Hall effect edge strips (2012)
Journal Article
Suddards, M., Baumgartner, A., Henini, M., & Mellor, C. J. (2012). Scanning capacitance imaging of compressible and incompressible quantum Hall effect edge strips. New Journal of Physics, 14, doi:10.1088/1367-2630/14/8/083015

We use dynamic scanning capacitance microscopy to image compressible and incompressible strips at the edge of a Hall bar in a two-dimensional electron gas (2DEG) in the quantum Hall effect (QHE) regime. This method gives access to the complex local c... Read More about Scanning capacitance imaging of compressible and incompressible quantum Hall effect edge strips.
