Audience Level General
Description Top-down and bottom-up methods are two types of approaches used in nanofabrication. In this course, synthesis techniques which are known as top-down approach are presented.
Overview
Top-down approach means a view from top(larger) to bottom(smaller). This approach is similar to making a statue made of stone. As in making of a statue, a bulk or big piece of stone is taken, similarly in top-down approach; a bulk piece of material is taken. Then carving and cutting is done until desired shape is achieved. Example: Different kinds of lithographic techniques include cutting, etching, grinding and ball milling technique.
In this course, top-down approach is taken into consideration. By the end of this course, students would be able to choose the right technique to achieve desired nanomaterial.
