Jun's Logbook
=Week of June 16=

__June 16__
Began overview and basic training for the Scanning Tunneling Microscope. There are three in the lab of Dr. Alex Kandel each using differing environmental conditions. One does the scanning under room conditions (room temperature, room pressure), a second creates a vacuum, and the third uses liquid helium and liquid nitrogen to lower the temperature to a few Kelvin as well as creating a vaccuum. All logbook entries and pictures are from the room condition STM unless noted.

A guide to STM usage is in progress and should be available soon.

Preliminary discussions were also held for a new experiment considering the effects of heat on the surface interactions of gold [Au(111)], octanethial, and coronene. The heat source is a laser.

Along with fellow student, Mrs. Lynda Rose, practice on using the STM continued. Several pictures were taken and towards the end of the week, both participants were competent users of the STM thanks to the guidance of graduate student Annette Raigoza.
