Comment on: "Microwave response of a two-dimensional electron stripe", cond-mat/0407364

Recently, S.A.Mikhailov et al presented a theoretical study(cond-mat/0407364) concerning the electromagnetic response of a finite-width two-dimensional electron stripe. Surprisingly, in the above manuscript the magnetic field dependence of the magnetoplasmon spectrum(namely Fig.4) reproduces that reported for the first time in our paper(cond-mat/0405176, JETP Lett., 80, August 2004, in press). We believe that the above curious coincidence may result from the authors not to be informed enough.

Influence of retardation effects on 2D magnetoplasmon spectrum

Within dissipationless limit the magnetic field dependence of magnetoplasmon spectrum for unbounded 2DEG system found to intersect the cyclotron resonance line, and, then approaches the frequency given by light dispersion relation. Recent experiments done for macroscopic disc-shape 2DEG systems confirm theory expectations.

Magnetotransport in dilute 2D Si-MOSFET system

The beating pattern of Shubnikov-de Haas oscillations is reproduced in both the crossed and tilted magnetic field configuration and in presence of zero-field valley splitting in Si-MOSFET system. The consequences of IQHE in extremely dilute 2DEG are discussed.

Quantum Hall Effect: the resistivity of a two-dimensional electron gas using a thermodynamic approach

Based on a thermodynamic approach, we have calculated the resistivity of a 2D electron gas, assumed $dissipationless$ in a strong quantum limit. Standard measurements, with extra current leads, define the resistivity caused by a combination of Peltier and Seebeck effects. The current causes heating(cooling) at the first(second) sample contacts, due to the Peltier effect. The contact temperatures are different. The measured voltage is equal to the Peltier effect-induced thermoemf which is linear in current. As a result, the resistivity is non-zero as $I\to 0$. The resistivity is a universal function of magnetic field and temperature, expressed in fundamental units $h/e^{2}$. The universal features of magnetotransport data observed in experiment confirm our predictions.

Thermal correction to resistivity in dilute 2D systems

We calculate the resistivity of 2D electron (hole) gas, taking into account the degeneracy and the thermal correction due to the combined Peltier and Seebeck effects. The resistivity is found to be universal function of temperature, expressed in units of $\frac{h}{e^{2}} (k_{F}l)^{-1}$. The giant parallel magnetiresistivity found to result from the spin and, if exists, valley splitting of the energy spectrum. Our analysis of compressibility and thermopower points to thermodynamic nature of metal-insulator transition in 2D systems.

Nonlinear regime of the current instability in a ballistic field effect transistor

The strongly nonlinear regime of Dyakonov-Shur instability is studied analytically and by computer simulations. The instability leads to high-amplitude stationary oscillations caused by shock wave formation in the FET channel. The numerically found shape and speed of the shock waves are well described in terms of the conventional hydrodynamics. The amplitude of stationary oscillations is determined.

Peltier effect induced longitudinal resistivity of ideal 2D electron(hole) gas in strong magnetic field

We demonstrate that in strong quantum limit the thermoelectric Peltier effect could define the longitudinal resistivity of dissipationless two-dimensional electron(hole) gas. The current results in heating(cooling) at first(second) Hall bar sample contact due to Peltier effect. At small current the contacts temperatures are different, the temperature gradient is linear on current. The voltage swing downstream the current is proportional to Peltier effect induced thermopower. As a result, nonzero longitudinal resistivity is measured in experiment. The above effect could exist in 3D case.

Ohm's law revision

The standard ohmic measurements by means of two extra leads contain an additional thermal correction to resistance. The current results in heating(cooling) at first(second) sample contact due to Peltier effect. The contacts temperatures are different. The measured voltage is the sum of the ohmic voltage swing and Peltier effect induced thermopower which is linear on current. As a result, the thermal correction to resistance measured exists at $I\to 0$. The correction should be in comparison with ohmic resistance. Above some critical frequency dependent on thermal inertial effects the thermal correction disappears.
