Tunneling phenomena in semiconductors and superconductors

Abstract

This dissertation presents the step of how to calculate the mathematical equation that is not difficult on the spreadsheet or EXCELL. It is can design a graph that shows the air flow for certain material. Spreadsheet can easily been use because it use a simple command. Spreadsheet also is the famous software in the engineering fields. It can calculate faster and accurately. As a result, it can save time. This dissertation also focuses on the equation to calculate the heat transfer in some certain material, for example chip-cooling. Simulation test has been done in solid work to show the air flow in and out from the certain material. Experiment to choose the suitable equation also has been done. The result shows that the spreadsheets have a capability to use all the equation that been choosing accurately, it also shows the air flow inside of certain material clearly.
