Quantum Carry Research of Q1D – SE on Helium at Charged Substrate

Abstract

Known in nano-electronic a solid state quantum - size systems motivate they creating using the surface electrons over helium. The quantum carry of a quasi-one-dimensional surface electrons (Q1D-SEs) over superfluid helium is considered here. The research have been performed in the electron gas region at conditions far from the electron quantum melting. A substrate is dense row of the optical fiber segments for SEs channels are situated in the gaps over helium. The substrate profile electrostatic model demonstrates modulation of potential in the electric field leading to possibility of the fibers tops charge thereby improving the Q1D-SEs channals quality. The experiments carried out by a low- frequency electron transport method in the  temperature range 1.5 K - 0.5 K at electron concentration up to 10⁹cm^-2.The SE transverse movement satisfies to the quantization condition taking a view both the temperature and the relaxation time of electron. Lower of some temperature the channels conductivity is a steps-like. The conductivity differential is peaks-like which qualitative correspondings to the electron states density with the peaks distance according to the 1D energy spectrum. Possibility apply the Q1D-SEs quantum levels as QBs of QC is considered.
