He also considers topological insulators, a new class of materials that could deliver sizable Rashba spin splitting in the surface electron spectrum
when implemented into a gated device structure.
For these purposes simple and exact methods to calculate the electron spectrum in quantum structures and the electron wave functions are of great interest.
The electron spectrum of [delta]-doped quantum wells can be calculated from solving the Schrodinger equation jointly with the Poisson one (SP) [28-35,38-47].
In this paper the combined TF-SP method to calculate the electron spectrum in [delta]-doped n-Si is presented at finite temperatures.
In the expression for the electron concentration the term due to the continuous electron spectrum [n.
This fact can be explained by a more essential influence of the continuous electron spectrum there.
While bumps in the cosmic ray electron spectrum have been measured before, they didn't cover the energy range seen in the ATIC experiment, Butt says.
Dan Hooper, a theoretical physicist at the University of Chicago, says the presence of another theoretical dark matter particle--the neutralino--could account for the bump in the cosmic ray electron spectrum.
Between all the various efforts, I think within the next two years, we should be able to say either yes or no as to whether or not these features seen in the electron spectrum are due to dark matter or something else.
NIST researchers recently have measured the single electron spectrum
of a semiconductor heterostructure containing InAs self-assembled quantum dots.
The authors measured the Compton-recoil electron spectrum
, first in the energy region of the so-called Compton profile and more recently in the regime of largest momentum transfer to the bound electrons.
Beacon, which will also sample the electron spectrum
over the poles, handles Polar BEAR's data transmissions.
