Quantum phase transitions in two-dimensional systems Page 1 Abstract. Experimental data on
quantum phase transitions in two-dimensional systems (superconductor – insulator, metal …

Low temperature cooling of two-dimensional electrons in silicon-metal-oxide semiconductor
field effect transistors is studied experimentally and found to be more effective than expected …

The temperature and density dependence of the phase coherence time τ ϕ in high-mobility
silicon inversion layers was determined from the magnetoresistivity due to weak localization …

We have measured the resistivity ρ of a dilute two-dimensional electron gas near the (111)
silicon surface as a function of a temperature. Since the valley degeneracy in such structures …

The structure of the Si (553) surface, tilted at-12.27 toward the (001) plane from the (111)
plane, has been studied by scanning tunneling microscopy (STM). The STM images reveal …

The ground-state compressibility of the two-dimensional electron gas is determined for the
density region which includes the fluid to localized phase transition. The behavior of the …

The principal focus of this thesis is on the development, construction and testing of a 300mK
ultra high vacuum (UHV) scanning tunneling microscope (STM), with the purpose of …

Under the above title Markovic et al.[Phys. Rev. B 62, 2195 (2000)] summarized their and
others' low-temperature data that show that a consistent underlying conduction mechanism …

В настоящее время имеется немало обзоров и даже книг (см., например,[1-9]),
посвященных квантовым фазовым переходам. В основном в них рассматриваются …
