Question

Nanoelectronics single atom transistor with comsol

Answer 1

Nanogap structures for molecular nanoelectronics … about the inverse of the quantum conductance 2e 2 /h = 77.6 μS and represents the conductance of a single atom of gold … The first one performs an absolute control over the initial resistance R 0 , and when (R - R 0 )/R 0 > 0.02 …

Answer 2

Answer:

An exact model for a single atom transistor was developed. Using two simplifying assumptions (1) that the device is restricted to a narrow conducting wire and (2) that the atom can be simulated by a point impurity potential, the model can be simplified considerably and an exact analytical solution can be derived.
