Torsional response and stiffening of individual multi-walled carbon nanotubes
P. A. Williams, S. J. Papadakis, A. M. Patel +3
We report on the characterization of torsional oscillators which use multi-walled carbon nanotubes as the spring elements. Through atomic-force-microscope force-distance measuremen…
Spin polarization and transition from metallic to insulating behavior in 2D systems
E. Tutuc, E. P. De Poortere, S. J. Papadakis +1
We have made quantitative measurements of the spin polarization of two-dimensional (2D) GaAs (100) electrons and GaAs (311)A holes, as a function of an in-plane magnetic field. The…
Low-field magnetoresistance in GaAs 2D holes
S. J. Papadakis, E. P. De Poortere, H. C. Manoharan +3
We report low-field magnetotransport data in two-dimensional hole systems in GaAs/AlGaAs heterostructures and quantum wells, in a large density range, $2.5 \times 10^{10} \leq p \l…
