Review and Analysis of Measurements of the Spin Hall Effect in Platinum

Luqiao Liu, R. A. Buhrman, D. C. Ralph

Several different experimental techniques have been used in efforts to measure the spin Hall conductivity and the spin Hall angle in Pt samples at room temperature, with results th…

Synchronous imaging for rapid visualization of complex vibration profiles in electromechanical microresonators

Yoav Linzon, Daniel J. Joe, Slava Krylov +4

Synchronous imaging is used in dynamic space-domain vibration profile studies of capacitively driven, thin n+ doped poly-silicon microbridges oscillating at rf frequencies. Fast an…

Entropic Spectral Broadening in Carbon Nanotube Resonators

Arthur W. Barnard, Vera Sazonova, Arend M. van der Zande +1

We simulated the behavior of suspended carbon-nanotube (CNT) resonators over a broad range of temperatures to address the unexplained spectral broadening and frequency shifts seen…

Ultrafast photocurrent measurement of the escape time of electrons and holes from carbon nanotube PN junction photodiodes

Nathaniel M. Gabor, Zhaohui Zhong, Ken Bosnick +1

Ultrafast photocurrent measurements are performed on individual carbon nanotube PN junction photodiodes. The photocurrent response to sub-picosecond pulses separated by a variable…

Very Slow Cooling Dynamics of Photoexcited Carriers in Graphene Observed by Optical-Pump Terahertz-Probe Spectroscopy

Jared H. Strait, Haining Wang, Shriram Shivaraman +3

Using optical-pump terahertz-probe spectroscopy, we study the relaxation dynamics of photoexcited carriers in graphene at different temperatures. We find that at lower temperatures…

Spatially, Temporally and Polarization-Resolved Photoluminescence Exploration of Excitons in Crystalline Phthalocyanine Thin Films

Naveen Rawat, Zhenwen Pan, Lane W. Manning +6

The lack of long range order in organic semiconductor thin films prevents the unveiling of the complete nature of excitons in optical experiments, because the diffraction limited b…

Tunable multi-photon Rabi oscillations in an electronic spin system

S. Bertaina, N. Groll, L. Chen +1

We report on multi-photon Rabi oscillations and controlled tuning of a multi-level system at room temperature (S=5/2 for Mn2+:MgO) in and out of a quasi-harmonic level configuratio…

Topological electric current from time-dependent elastic deformations in graphene

Abolhassan Vaezi, Nima Abedpour, Reza Asgari +2

We show the possibility of inducing an edge charge current by applying time-dependent strain in gapped graphene samples preserving time reversal symmetry. We demonstrate that this…

Uniform Peak Optical Conductivity in Single-Walled Carbon Nanotubes

Jesse M. Kinder, Jiwoong Park, Garnet Kin-Lic Chan

Recent measurements in single-walled carbon nanotubes show that, on resonance, all nanotubes display the same peak optical conductivity of approximately 8 , independent of r…
