Sum Frequency Generation (SFG) Systems
Our lab has three SFG laser systems. Two of the systems use picosecond laser systems and are used to study molecular behavior at static
interfaces. The third, newer system, uses a femtosecond laser system which allows us to study molecular behavior at dynamic
interfaces.
Biaxial Friction Cell
We have assembled a biaxial friction cell capable of measuring friction behavior at various interfaces. The cell can also be coupled
with an optical microscope or the SFG systems to perform in situ spectroscopy and microscopy measurements.
High Vacuum Pulsed Plasma Polymerization Chamber
The high vacuum pulsed plasma chamber is used for chemical modification of surfaces and controlled surface chemistry.
X-ray Photoelectron Spectroscopy (XPS) System
The XPS system is used to study molecular orientation and crystallization of materials.
Wilhelmy Microbalance
The Wilhelmy Microbalance is used to measure the surface tension of various liquids.
CVD System
The CVD system is made up of a three zone tube furnace and gas/vapor flow control. The tube furnace has three programmable temperature
zones for accurate temperature control needed for carbon nanotube growth and other CVD processes .
High Vacuum Electrical Test Chamber and Keithley Instruments
Our lab is equipped with a new high vacuum chamber for testing electrical properties such as electron emission. We also have a high
resolution Keithley Sourcemeter which is used to source and measure electrical properties through computer applications designed in Labview.
