Sum Frequency Generation (SFG) Systems

SFG Laser 1

SFG Laser 2

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

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

Plasma Chamber

The high vacuum pulsed plasma chamber is used for chemical modification of surfaces and controlled surface chemistry.

X-ray Photoelectron Spectroscopy (XPS) System

XPS system

The XPS system is used to study molecular orientation and crystallization of materials.

Wilhelmy Microbalance

Wilhelmy Microbalance

The Wilhelmy Microbalance is used to measure the surface tension of various liquids.

CVD System

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

FET Vacuum Chamber

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.
