Transverse Conductivity in the Sliding Charge-Density-Wave State of NbSe 3
Physical review letters, 2012Co-Authors: A. A. Sinchenko, P. Monceau, T. CrozesAbstract:The dynamical properties of longitudinal and Transverse conduction of ${\mathrm{NbSe}}_{3}$ single crystals have been simultaneously studied when the current is applied along the $b$ axis (chain direction). In the vicinity of the threshold electric field for charge-density-wave sliding, the Transverse conduction sharply decreases. When a rf field is applied, voltage Shapiro steps for longitudinal transport are observed as usual but also current Shapiro steps in the Transverse direction. The possible mechanisms of this effect are discussed.

Transverse Conductivity behavior at threshold electric field for CDW sliding in NbSe3
Physica B: Condensed Matter, 2012Co-Authors: A. A. Sinchenko, P. Monceau, T. CrozesAbstract:Abstract We have measured the dynamical properties which occur in the Transverse direction to the conducting chains in NbSe 3 single-crystals, when the CDW slides along the chains. A sharp decrease in Transverse Conductivity takes place above an electric field less than the longitudinal threshold one for CDW sliding; that may result from induced phase shifts between CDW chains. Under the joint application of dc and rf driving fields voltage Shapiro steps for longitudinal transport are observed as usual but also pronounced current Shapiro steps in Transverse direction. The possible mechanisms of this effect as well as a tentative new view on the origin of the narrow band noise in CDW compounds are discussed.

Narrow stripe-width, low-ridge high power quantum cascade lasers
Applied Physics Letters, 2007Co-Authors: Arkadiy Lyakh, Peter S. Zory, Daniel Wasserman, G. Shu, Claire F. Gmachl, M. D'souza, Dan Botez, David P. BourAbstract:Narrow stripe-width, low-ridge quantum cascade lasers operating at 5.3μm were fabricated from InP-based, metal-organic chemical-vapor-deposition-grown material. Maximum peak-pulsed output power of 12W at 14A was measured from a low-ridge laser with a high reflectivity coated back facet. Modeling shows that the lateral variation of the Transverse Conductivity is essential for an accurate description of the current spreading in these devices.

Narrow stripe-width, low-ridge configuration for high power quantum cascade lasers
2007 Conference on Lasers and Electro-Optics (CLEO), 2007Co-Authors: Arkadiy Lyakh, Peter S. Zory, Daniel Wasserman, G. Shu, Claire F. Gmachl, M. D'souza, Dan Botez, David P. BourAbstract:Low-ridge-configuration, quantum-cascade lasers operating at 5.3 mum provide, at 80 K, 12 W peak-pulsed power at 14 A drive. A model of current spreading that takes into account the lateral variation in Transverse Conductivity adequately explains the results.
