A tunable carbon nanotube electromechanical oscillator
Vera Sazonova, Yuval Yaish, Hande Ustunel +3
Nanoelectromechanical systems (NEMs) hold promise for a number of scientific and technological applications. In particular, NEMs oscillators have been proposed for use in ultrasens…
Measuring electron orbital magnetic moments in carbon nanotubes
E. D. Minot, Yuval Yaish, Vera Sazonova +1
The remarkable transport properties of carbon nanotubes (NTs) are determined by their unique electronic structure (1). The electronic states of a NT form one-dimensional electron a…
Electrical Nanoprobing of Semiconducting Carbon Nanotubes using an Atomic Force Microscope
Y. Yaish, J. -Y. Park, S. Rosenblatt +3
We use an Atomic Force Microscope (AFM) tip to locally probe the electronic properties of semiconducting carbon nanotube transistors. A gold-coated AFM tip serves as a voltage or c…
Tuning carbon nanotube bandgaps with strain
E. D. Minot, Yuval Yaish, Vera Sazonova +3
We show that the band structure of a carbon nanotube (NT) can be dramatically altered by mechanical strain. We employ an atomic force microscope tip to simultaneously vary the NT s…
Two band transport and the question of a metal-insulator transition in GaAs/GaAlAs two dimensional holes
Yuval Yaish, Oleg Prus, Evgeny Buchstab +4
The magnetotransport of two dimensional holes in a GaAs/AlGaAs heterostructure is studied experimentally and theoretically. Spin-orbit splitting of the heavy hole band is manifeste…
