Magnetic properties of edge channels of silicon nanosandwich structures with deposited DNA oligonucleotides

Abstract

Measurements of the field dependences of the static magnetic susceptibility demonstrate de Haas-Van Alphen and Aharonov-Bohm oscillations at high temperatures and low magnetic fields in silicon nanosandwich structures (SNS). In the case of the deposition of DNA oligonucleotides into the edge channels of the SNS, a change in the oscillation period is observed. The possibilities of using the obtained data to identify the properties of DNA oligonucleotides are discussed. Keywords: THz radiation, DNA identification, de Haas-Van Alphen, Aharonov-Bohm.
