Universal behaviour of the thermoelectric power of composite fermions
TLDR
In this paper, the thermopower of high-mobility two-dimensional electron gases at even denominator filling factors v are found to be remarkably similar to each other and also to the thermopsower at zero magnetic field.About:

Magnetothermoelectric effects in semiconductor systems
TL;DR: A review of the magnetothermoelectric properties of semiconductors can be found in this article, where the main conclusion is that the experimental observations on electrons, holes, two-carrier systems and composite fermions are consistent with physical models and predictions based on the Boltzmann equation.

Theory of the half-filled Landau level.
TL;DR: In this article, a two-dimensional electron system in an external magnetic field, with Landau-level filling factor \ensuremath{
u}=1/2, can be transformed to a mathematically equivalent system of fermions interacting with a Chern-Simons gauge field such that the average effective magnetic field acting on the fermion is zero.

Experimental demonstration of a Fermi surface at one-half filling of the lowest Landau level.
TL;DR: The first direct observation of the cyclotron motion of new quasiparticles in a 2D electron system near 1/2 filling factor is reported, and resonance of a surface sound wave with cyclotrons orbits of charge carriers is observed.
