Parametric Resonance and RF-to-THz Frequency Conversion in Semiconductor Plasmonic Crystals
G. R. Aizin, J. Mikalopas, M. Shur
We show that plasma excitations in nanoscale field-effect transistor structures with periodic alternation of gated and ungated regions (plasmonic crystals) differ fundamentally fro…
Abundance, Sizes, and Major Element Compositions of Components in CR and LL Chondrites: Formation from Single Reservoirs
Denton S. Ebel, Marina E. Gemma, Samuel P. Alpert +3
Abundances, apparent sizes, and individual chemical compositions of chondrules, refractory inclusions, other objects and surrounding matrix have been determined for Semarkona (LL3.…
Properties of Original Impactors Estimated from Three-Dimensional Analysis of Whole Stardust Tracks
Michael Greenberg, Denton S. Ebel
The Stardust mission captured comet Wild 2 particles in aerogel at 6.1 km/sec. We performed high resolution three-dimensional imaging and X-ray fluorescence mapping of whole cometa…
Thermochemical Stability of Low-Iron, Manganese-Enriched Olivine in Astrophysical Environments
Denton S. Ebel, Michael K. Weisberg, John R. Beckett
Low-iron, manganese-enriched (LIME) olivine grains are found in cometary samples returned by the Stardust mission to comet 81P/Wild 2. Similar grains are found in primitive meteori…
Abundance, Major Element Composition and Size of Components and Matrix in CV, CO and Acfer 094 Chondrites
Denton S. Ebel, Chelsea Brunner, Kevin Konrad +7
The relative abundances and chemical compositions of the macroscopic components or "inclusions" (chondrules and refractory inclusions) and fine-grained mineral matrix in chondritic…
Plasma Instability and Amplified Mode Switching Effect in THz Field Effect Transistors with Grating Gate
G. R. Aizin, J. Mikalopas, M. Shur
We developed a theory of collective plasma oscillations in a dc current-biased field effect transistor with interdigitated dual grating gate and demonstrated a new mechanism of ele…
