Purpose: of this paper is to justification the most rational method for the nanostructures
synthesis on the semiconductors surface, which is capable of providing high quality
synthesized nanostructures at low cost and ease of the process.
Design/methodology/approach: The choice of the optimal method of synthesis was
carried out using the hierarchy analysis method, which is implemented by decomposing the
problem into more simple parts and further processing judgments at each hierarchical level
using pair comparisons.
Findings: The article describes the main methods of synthesis of nanostructures, presents
their advantages and disadvantages. The methods were evaluated by such criteria
as: environmental friendliness, efficiency, stages number of the technological process,
complexity, resources expenditure and time and effectiveness. Using the hierarchy analysis
method, has been established that electrochemical etching is the most important alternative,
and when choosing a nanostructures synthesis method on the semiconductors surface, this
method should be preferred. Such studies are necessary for industrial serial production of
nanostructures and allow reducing expenses at the realization of the problem of synthesis
of qualitative samples.
Research limitations/implications: In this research, the hierarchy analysis method was
used only to select a rational method for synthesizing nanostructures on the semiconductors
surface. However, this research needs to be developed with respect to establishing a
correlation between the synthesis conditions and the nanostructures acquired properties.
Practical implications: First, was been established that the optimal method for the
nanostructures synthesis on the semiconductors surface is electrochemical etching, and
not lithographic or chemical method. This allowed the theoretical and empirical point of
view to justify the choice of the nanostructures synthesis method in the industrial production
conditions. Secondly, the presented method can be applied to the synthesis method choice
of other nanostructures types, which is necessary in conditions of resources exhaustion and
high raw materials cost.
Originality/value: In the article, for the first time, the choice of the nanostructures
synthesis method on the semiconductors surface is presented using of paired comparisons
of criteria and available alternatives. The article will be useful to engineers involved in the
nanostructures synthesis, researchers and scientists, as well as students studying in the
field of "nanotechnology".
