Lab 6

May 23, 2014

Today our lab consisted of examining our substrates under the Scanning Electron Microscope (SEM).

Microscope

A fairly simple lab today, mostly watching and observing. The substrates were placed into the vacuum sealed chamber to examine them underneath the electron microscope seen in Figure 1. The microscope essentially works by bombarding the object with electrons. The electrons that actually collide with the object are then bounced back and the computer constructs an image of the object from the bounced back electrons.

When done with our substrates, the computer produced the image in Figure 2 for our 30 cycle substrate and Figure 3 for our 90 cycle substrate.
