Photoresonance and conductivity of surface electrons on liquid ³He
Resonance variations of the in-plane conductivity of surface electrons (SEs) over liquid ³He induced by microwave (MW) radiation of a fixed frequency are experimentally and theoretically studied for low temperature scattering regimes (T < 0.5 K). The system was tuned to resonance by varying the...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Resonance variations of the in-plane conductivity of surface electrons (SEs) over liquid ³He induced by
microwave (MW) radiation of a fixed frequency are experimentally and theoretically studied for low temperature
scattering regimes (T < 0.5 K). The system was tuned to resonance by varying the amplitude of the
vertical electric field which shifts the positions of SE Rydberg levels. The line-shape change and reversing
of the sign of the effect are found to be opposite to that reported previously for weak vertical electric fields.
A theoretical analysis of conductivity of the SE system heated due to decay of electrons excited to the second
Rydberg level by the MW explains well the line-shape variations observed. It shows also that shifting
the MW resonance into the range of weak vertical fields leads to important qualitative changes in the
line-shape of SE conductivity which are in agreement with observations reported previously. |
