Multiple Remotely Sensed Lines of Evidence for a Depleting Seasonal Snowpack in the Near East

Remote Sensing, 2019
The snow-fed river basins of the Near East region are facing an urgent threat in the form of declining water resources. In this study, we analyzed several remote sensing products (optical, passive microwave, and gravimetric) and outputs of a ...

Tuning Nanocrystal Surface Depletion by Controlling Dopant Distribution as a Route Toward Enhanced Film Conductivity

, 2018
Electron conduction through bare metal oxide nanocrystal (NC) films is hindered by surface depletion regions resulting from the presence of surface states.

Decaying equatorial F region plasma depletions [PDF]

Journal of Geophysical Research: Space Physics, 1997
We analyze plasma density data from the AE‐E satellite to determine how F region irregularities decay. This satellite had a low inclination orbit that was ultimately circular at an altitude of 434 km. It frequently observed plasma depletions in the postsunset regime during spread F conditions, sometimes along a trajectory affording a “horizontal cut ...

Surface-Potential-Based Drain Current Model of Gate-All-Around Tunneling FETs

IEEE Journal of the Electron Devices Society
A closed-form, analytical, and unified model for the surface potential from source to drain in nanowire (NW) gate-all-around (GAA) tunneling field effect transistors (TFETs) is proposed and validated.

The Oil and Gas Industry and the Niger Delta: Implications for the Environment

Journal of Applied Sciences and Environmental Management, 2010
The causes of environmental degradation and biodiversity depletion arising from the activities of the oil industry in the region are evaluated. The authors argue that, specific negative impact on the region arising from the activities of the industries ...

Spin-Polarized Electron Transport at Ferromagnet/Semiconductor Schottky Contacts

, 2003
We theoretically investigate electron spin injection and spin-polarization sensitive current detection at Schottky contacts between a ferromagnetic metal and an n-type or p-type semiconductor.

Identifying water mass depletion in northern Iraq observed by GRACE [PDF]

Hydrology and Earth System Sciences, 2015
Observations acquired by Gravity Recovery And Climate Experiment (GRACE) mission indicate a mass loss of 146 ± 6 mm equivalent water height (EWH) in northern Iraq between 2007 and 2009.

Capacitance response of solar cells based on amorphous Titanium dioxide (A-TiO₂) semiconducting heterojunctions

AIMS Materials Science, 2021
In the present study, we studied the capacitance frequency response of amorphous titanium dioxide (A-TiO2)/poly(3-hexylthiophene) (P3HT) solar cells. The capacitance was measured to provide information on interfacial layer between the two materials. At a

The t-J model on a semi-infinite lattice

, 2010
The hole spectral function of the t-J model on a two-dimensional semi-infinite lattice is calculated using the spin-wave and noncrossing approximations. In the case of small hole concentration and strong correlations, $t\gg J$, several near-boundary site

What is the Total Deuterium Abundance in the Local Galactic Disk? [PDF]

, 2006
Analyses of spectra obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite, together with spectra from the Copernicus and IMAPS instruments, reveal an unexplained very wide range in the observed deuterium/hydrogen (D/H) ratios for ...
