Confinement effects on decay rate of surface electron states over liquid helium
The decay rate of excited states of surface electrons in liquid helium, trapped in a quantum dot system, is evaluated, taking into account the process of spontaneous radiation of two-ripplons with short wavelength. We find that the values of the decay rate in later process are rather higher than t...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The decay rate of excited states of surface electrons in liquid helium, trapped in a quantum dot system, is
evaluated, taking into account the process of spontaneous radiation of two-ripplons with short wavelength.
We find that the values of the decay rate in later process are rather higher than those for the one-ripplon process
previously calculated. The upper-bound limit lifetime of excited states of surface electrons in a quantum
dot is found to be τ<10⁻⁶–10⁻⁷ s. |
