Sensitivity characteristics of germanene

Abstract

In this paper, we investigate a sensitivity characteristics of germanene based on the tunneling current in the contact of a germanene with a metal or a superlattice. It is shown, that the sensitivity of the considered system to impurity molecules increases when a constant electric field is applied to it along the germanene plane.

Tunneling current of contact of fractal object with metal and superlattice

“…Although the tunneling current measurement method itself has a number of disadvantages (the distance between the samples determines the current, the degree of "roughness" of the samples, etc. ), in our opinion, it has the advantage that it allows optimizing the choice of the second sample to achieve the highest sensitivity (for example, see [20]). In this paper, fractals are considered on the basis of two-dimensional lattices, and the formalism allows generalization to the case of a higher dimension.…”
