Observing the Quantization of Zero Mass Carriers in Graphene

Author(s)
Joseph A. Stroscio, Gregory M. Rutter, D. L. Miller, K. Kubista, W. A. de Heer, Phillip N. First
Application of a magnetic field to conductors causes the charge carriers to circulate in cyclotron orbits with quantized energies called Landau levels (LLs)

SERS not to be taken for granted in the presence of oxygen

Author(s)
Melek Erol, Yun Han, Scott K. Stanley, Christopher Stafford, Henry Du, Svetlana Sukhishvili
In this communication, we report that oxidation of the Ag nanoparticle (Ag NP) surface under ambient conditions has a dramatic effect on the adsorption and SERS

Time domain measurement of phase noise in a spin torque oscillator

Author(s)
Mark W. Keller, Anthony B. Kos, Thomas J. Silva, William H. Rippard, Matthew R. Pufall
We measure phase noise from the zero crossings of the voltage vs. time waveform of a spin torque nanocontact oscillating in a vortex mode. The power spectrum of

Linking Air and Vacuum Mass Measurement by Magnetic Levitation

Author(s)
Zeina J. Kubarych, Patrick J. Abbott, Edwin R. Williams, Ruimin Liu, Vincent J. Lee, Hung-Kung Liu
This paper describes a new approach to directly link air and vacuum mass measurements using magnetic levitation techniques. This procedure provides direct

William Sparks, James H. Hough, Thomas Germer, Feng Chen, Shiladitya DasSarma, Priya DasSarma, Frank Robb, Nadine Manset, Ludmilla Kolokolova, Neill Reid, F. D. Macchetto, William Martin
The identification of a universal biosignature that could be sensed remotely is critical to the prospects for success in the search for life elsewhere in the

Dipolar Chains formed by synthesized cobalt nanocubes

Author(s)
Guangjun Cheng, Robert D. Shull, Angela R. Hight Walker
Cobalt nanocubes with an average edge length of 50 nm and the epsilon crystalline structure were synthesized via thermo-decomposition in 1,2-dichlorobenzene at
