Bioelectronic Systems for Neurosensing Enabled by Graphene

Creator:: Fengel, Carly V.
Abstract:: Taking long-term electrical measurements of a large number of neurons simultaneously is required for many modern neuroscience experiments. However, such experiments are currently limited by the shortcomings of traditional neurosensing technology. For example, there is a significant mechanical mismatch between rigid silicon probes and soft biological tissues. This mismatch can...

Beating Modes in Protostellar Disks

Creator:: Varga, Attila V.
Abstract:: Computational simulations of disks are becoming an important tool to predict the the evolution of protostars and disks to better understand the formation of planets. Past research has shown that the evolution of disks and their protostar can be altered through the interaction between gravity and hydrodynamic instabilities. We perform...

Universal interaction-driven gap in metallic carbon nanotubes

Creator:: Senger, Mitchell J., McCulley, Daniel R., Lotfizadeh, Neda, Deshpande, Vikram V., and Minot, Ethan D.
Abstract:: Suspended metallic carbon nanotubes (m-CNTs) exhibit a remarkably large transport gap that can exceed 100 meV. Both experiment and theory suggest that strong electron-electron interactions play a crucial role in generating this electronic structure. To further understand this strongly-interacting system, we have performed electronic measurements of suspended m-CNTs with known...

Using fundamental measure theory to treat the correlation function of the inhomogeneous hard-sphere fluid

Creator:: Schulte, Jeff B., Kreitzberg, Patrick A., Haglund, Chris V., and Roundy, David
Abstract:: We investigate the value of the correlation function of an inhomogeneous hard-sphere fluid at contact. This quantity plays a critical role in statistical associating fluid theory, which is the basis of a number of recently developed classical density functionals. We define two averaged values for the correlation function at contact...

Red electroluminescence from ZnGaS:Mn thin films

Creator:: Dimitrova, V., Draeseke, A., Tate, J., Yokoyama, T., Clark, B. L., Keszler, Douglas A., and Tate, Janet
Abstract:: We demonstrate color shifting from the yellow to the red in the electroluminescence from (ZnGa)S:Mn films. We observe threshold voltages down to about 35 V, extremely low for such devices. We discuss the materials characteristics of the phosphor films, and the potential for improvement of the luminous intensity of the...

Generation of multicycle terahertz pulses via optical rectification in periodically inverted GaAs structures

Creator:: Lee, Yun-Shik, Hurlbut, Walter C., Vodopyanov, K. L, Fejer, M. M., and Kozlov, V. G.
Abstract:: The authors demonstrate the generation of multicycle narrow-bandwidth terahertz pulses in periodically inverted GaAs structures using optical rectification of 2 μm, 100 fs pump pulses. Three different types of orientation-inverted samples are employed: optically contacted multilayer, orientation-patterned, and diffusion-bonded GaAs. The terahertz pulses are characterized by two-color (pump at 2...

Terahertz-wave generation in quasi-phase-matched GaAs

Creator:: Vodopyanov, K. L., Fejer, M. M., Yu, X., Harris, J. S., Lee, Yun-Shik, Hurlbut, Walter C., Kozlov, V. G., Bliss, D., and Lynch, C.
Abstract:: The authors demonstrate an efficient room temperature source of terahertz radiation using femtosecond laser pulses as a pump and GaAs structures with periodically inverted crystalline orientation, such as diffusion-bonded stacked GaAs and epitaxially grown orientation-patterned GaAs, as a nonlinear optical medium. By changing the GaAs orientation-reversal period (504–1277 μm), or...
