• #### Electron correlation in extended systems via quantum embedding ﻿

(2015-06-17)
The pursuit of accurate and computationally efficient many-body tools capable of describing electron correlation is a major effort of the quantum chemistry community. The accuracy of chemical predictions strongly depends ...
• #### Electron doping evolution of structural and antiferromagnetic phase transitions in NaFe1−xCoxAs iron pnictides ﻿

(2016)
We use transport and neutron diffraction to study the electronic phase diagram of NaFe1−xCoxAs. In the undoped state, NaFeAs exhibits a tetragonal-to-orthorhombic structural transition below Tsfollowed by a collinear ...
• #### Electron dynamics in single-walled carbon nanotubes ﻿

(2010)
This thesis looks at three aspects of electron dynamics in single-walled carbon nanotubes (SWNTs): electron spin resonance (ESR), conductivity, and the dynamic Franz-Keldysh effect (DFKE). The temperature dependence of ESR ...
• #### Electron emission from aluminum as a result of plastic strain ﻿

(1958)
Aluminum was strained in tension under a Geiger counter. Electron emission associated with plastic deformation and subsequent delayed emission was observed. The specimens were illuminated during both the growth and decay ...
• #### Electron Energy Loss Spectroscopy and Optical Properties of Plasmonic Nanostructure ﻿

(2015-04-15)
Plasmon is considered to be the incompressible self-oscillation of conducting electrons in small nanoparticles. A classical spring model could be used to describe plasmon’s behavior. Many different techniques have been ...

• #### Electron phase coherence in mesoscopic normal metal wires ﻿

(2007)
Corrections to the classically predicted electrical conductivity in normal metals arise due to the quantum mechanical properties of the conduction electrons. These corrections provide multiple experimental tests of the ...
• #### Electron polarization in beta decay and internal conversion ﻿

(1959)
The general theory for beta decay is developed in section 2 using a consistent normalization and phase convention for the lepton wave functions; these phases are not consistent in the literature. The resulting general ...
• #### Electron Screening and Kinetic-Energy Oscillations in a Strongly Coupled Plasma ﻿

(1969)

(1972)
• #### Electron transfer in K(nd) collisions with attaching molecules at low-to-intermediate n ﻿

(1990)
Negative ion formation via electron transfer in thermal energy collisions between K(nd) Rydberg atoms and simple polyatomic molecules is studied at low-to-intermediate values of principal quantum number, n (n $<$ 40). At ...
• #### Electron transport in ferromagnetic nanostructures ﻿

(2008)
As the size of a physical system decreases toward the nanoscale, quantum mechanical effects such as the discretization of energy levels and the interactions of the electronic spins become readily observable. To understand ...
• #### Electron tunneling rates between an atom and a corrugated surface ﻿

(2001)
We introduce a new method for calculating the broadening of atomic levels as a function of the atom's position outside the surface. The surface is studied using a cluster model, and the adsorbate-cluster eigenproblem is ...
• #### Electron-Spin Polarization at Single-Crystalline Cr and Ni Surfaces Determined with Electron-Capture Spectroscopy ﻿

(1981)
The spin polarization P of electrons at Cr and Ni surfaces is measured with electron-capture spectroscopy. With use of one-electron capture at magnetized Cr(100)-c(2×2) surfaces at 293 K (TN=310 K), P values up to -18% are ...

(1978)
• #### Electron-Temperature Evolution in Expanding Ultracold Neutral Plasmas ﻿

(2007-08-17)
• #### ELECTRONIC AND CARS SPECTROSCOPY OF GAS PHASE TRANSIENTS: PHOTODYNAMICS OF AZOMETHANE AND PYRIDAZINE ﻿

(1985)
An apparatus has been constructed to perform gas phase excited state spectroscopy and dynamics with nanosecond time resolution. Two different transient spectroscopic techniques were employed to study azomethane and pyridazine. ...
