On initial enhancement of mesospheric dust associated plasma irregularities subsequent to radiowave heating
(Copernicus Publications, 2008)
Important observational manifestations of subvisible mesospheric dust are Polar Mesospheric Summer Echoes PMSE which are produced by scattering from electron irregularities produced by dust charging. It has been observed ...
Structural properties and band offset determination of p-channel mixed As/Sb type-II staggered gap tunnel field-effect transistor structure
(AIP Publishing, 2012-09-01)
The structural properties and band offset determination of p-channel staggered gap In0.7Ga0.3As/GaAs0.35Sb0.65 heterostructure tunnel field-effect transistor (TFET) grown by molecular beam epitaxy (MBE) were investigated. ...
Characterizing ultrashort optical pulses using second-order nonlinear nanoprobes
(AIP Publishing, 2010-12-01)
We report a second-order nonlinear nanoprobe for characterizing ultrafast optical near fields. The proposed nanoprobe comprises second harmonic nanocrystals attached to a carbon nanotube, which is in turn attached to a ...
Transmission of evanescent wave modes through a slab of negative-refractive-index material
(American Physical Society, 2011-02-28)
There has been a long-standing argument about Pendry's suggestion that a plane harmonic evanescent (surface) wave along the interface between free space and a slab of epsilon = -1, mu = -1 double-negative (DNG) medium will ...
Development of a nonlinear nanoprobe for interferometric autocorrelation based characterization of ultrashort optical pulses
(AIP Publishing, 2010-01-01)
Near-field scanning can achieve nanoscale resolution while ultrashort pulse diagnostic tools can characterize femtosecond pulses. Yet currently it is still challenging to nonperturbatively characterize the near field of ...
High quality Ge thin film grown by ultrahigh vacuum chemical vapor deposition on GaAs substrate
(AIP Publishing, 2011-04-01)
High-quality epitaxial Ge films were grown on GaAs substrates by ultrahigh vacuum chemical vapor deposition. High crystallinity and smooth surface were observed for these films by x-ray diffraction, transmission electron ...
Fermi level unpinning of GaSb (100) using plasma enhanced atomic layer deposition of Al2O3
(AIP Publishing, 2010-10-01)
N-type and p-type GaSb metal-oxide-semiconductor capacitors (MOSCAPs) with atomic-layer-deposited (ALD) and plasma-enhanced-ALD (PEALD) Al2O3 dielectrics are studied to identify the optimum surface preparation and oxide ...
The influences of surface treatment and gas annealing conditions on the inversion behaviors of the atomic-layer-deposition Al2O3/n-In0.53Ga0.47As metal-oxide-semiconductor capacitor
(AIP Publishing, 2010-07-01)
The inversion behaviors of atomic-layer-deposition Al2O3/n-In0.53Ga0.47As metal-oxide-semiconductor capacitors are studied by various surface treatments and postdeposition annealing using different gases. By using the ...
Ultra-high frequency photoconductivity decay in GaAs/Ge/GaAs double heterostructure grown by molecular beam epitaxy
(AIP Publishing, 2013-03-01)
GaAs/Ge/GaAs double heterostructures (DHs) were grown in-situ using two separate molecular beam epitaxy chambers. High-resolution x-ray rocking curve demonstrates a high-quality GaAs/Ge/GaAs heterostructure by observing ...
Reduced erbium-doped ceria nanoparticles: one nano-host applicable for simultaneous optical down- and up-conversions
(Springer, 2014-05-13)
This paper introduces a new synthesis procedure to form erbium-doped ceria nanoparticles (EDC NPs) that can act as an optical medium for both up-conversion and down-conversion in the same time. This synthesis process results ...
