Antireflection coated semiconductor laser amplifier for Bose-Einstein condensation experiments
We present a slave laser highly suitable for the preparation and detection of 87Rb Bose-Einstein condensates (BEC). A highly anti-reflection coated laser diode serves as an optical amplifier, which requires neither active temperature stabilization nor ...

Electronic Structure of GaAs [PDF]
Using a nonlocal pseudopotential, including spin-orbit interactions, we have calculated a band structure for GaAs which is in excellent agreement with electroreflectance, wave-length-modulation, and photoemission experimental results. As in a calculation by Pandey and Phillips, an order of magnitude in accuracy has been gained over existing band ...

Effect of Ground Plane Deformation on Electrical Performance of Air Microstrip Antennas
This paper covers the variation of electrical performance of air microstrip antennas due to its ground plane deformation. A typical sinusoidal function is utilized to characterize the shape of deformation, based on which different shapes of ground plane ...

On the Structure of the Electron
Usually the electron is described as a mathematical point with charge, mass, spin angular momentum, and electromagnetic field. Because of the unbounded energies this causes mathematical difficulties [1]. These can be avoided by considering a finite radius.

Electronic structure of MnSb [PDF]
Self-consistent, spin-polarized energy-band calculations have been performed for MnSb, for both ferromagnetic and antiferromagnetic spin alignments. For ferromagnetic MnSb we find a 3d5.5 configuration on the Mn atom, with a magnetic moment of 3.3μB on the Mn sites, and –0.06μB on the Sb sites. The charge transfer of Mn to Sb is very small.

Electronic transport through ordered and disordered graphene grain boundaries [PDF]
The evolution of electronic wave packets (WPs) through grain boundaries (GBs) of various structures in graphene was investigated by the numerical solution of the time-dependent Schrödinger equation. WPs were injected from a simulated STM tip placed above
