In a reciprocal approach, we will exploit the many-body nature of optical excitations in a two-dimensional electron gas
to enhance polariton-polariton interactions.
Until recently subwavelength optics laid great hopes on the effects related to interactions of light with the, so-called, plasmons -- collective oscillations of free electron gas
The electrons harbored at the interface form a sheet of charges, called two-dimensional electron gas
In this context, we consider an electron gas
consisting of n free electrons with mass [m.
These electrons are referred to as a two-dimensional electron gas
Here, we study the origin of this apparent discrepancy, focusing on Lindhard's formula for the transverse response of the electron gas
Other subjects covered include electron gas
oscillations in plasma theory and applications, effects of suction and injection on magnetohydrodynamic heat transfer in stagnation point flow with variable body temperature, and multiharmonic treatment of non-resonant growing of electromagnetic wave amplified by energetic electrons with ring-beam distribution.
To make measurements of electronic flow, some researchers have forced an electron gas
to pass through a narrow, electrically defined gap, before permitting the electrons to spread out again.
Some of the electrons in the gold are not anchored to individual atoms but instead form a free-floating electron gas
, explained Xia.
Seven articles are devoted to problems in electron gas
and semiconductor heterostructures.
Sunyaev and Zel'dovich predicted that hot electron gas
in clusters scatters the CMBR, creating spectral distortions.
Objective: In the last decade experimental and theoretical studies in condensed matter demonstrated that materials with strong spin-orbit coupling can host a new state of matter for the electron gas
- a topological insulator.
