Temperature bistability in a 2D electron system on liquid helium induced by Coulomb interaction under cyclotronresonance excitation
The energy balance of strongly interacting surface electrons on liquid helium under cyclotron-resonance excitation
 is theoretically studied. The Coulomb interaction is shown to induce temperature bistability of the electron
 system, if the magnetic field and electron density are hig...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The energy balance of strongly interacting surface electrons on liquid helium under cyclotron-resonance excitation
is theoretically studied. The Coulomb interaction is shown to induce temperature bistability of the electron
system, if the magnetic field and electron density are high enough. Surprisingly, bistability appears already for
quite low average kinetic energies, when nearly all electrons occupy the ground surface subband. The electron
temperature Te, as the function of the magnetic field B, exhibits hysteresis and bistability jumps in a certain
range of the microwave power. Above the threshold microwave field, the line shape Te(B) is shown to be sensitive
to details of the ripplon dispersion at large wave numbers.
