Bottom-Up approach
Category General
Difficulty Level Normal
Audience Level General
Description Top-down and bottom-up methods are two approaches used in nanofabrication. In this course, synthesis techniques which are known as bottom-up approach are presented.
Overview
Bottom-up approach means a view from bottom(smaller) to top or up(larger). In this technique, a nanometric structure is formed by using methods of assembly or self-assembly. For example: all cells use enzymes to create DNA by taking constituent molecules and binding them together to make the final component. Moreover, the bottom-up approach provides the possibility for creating hierarchical and ordered nanostructures because of physicochemical interactions and self-assembly of molecules.

Booklet
Description
 It starts with an introduction to evaporation deposition, gives some general information, talks about the mechanism and product properties. It ends with talking about advantages and disadvantages.
Mental Challenge
 The word doesn’t show any difference from PVD. What is their difference?
